This movie should be called: Back to the Past. And it should have been directed by Robert Zemeckis. It's a shame the Americans didn't make this movie. But probably Hollywood would have ruined the book. Here's the important missing scene: He shoved his 11ps out and looked judicial. "Our instructions for this client do not read to wake her today." "No?" I felt disappointed and hurt. "No. Her exact wishes are as follows: instead of necessarily being waked today, she wished not to be waked at all until you showed up." He looked me over and smiled. "You must have a heart of gold. I can't account for it on your beauty." I sighed. "Thanks, Doctor." "You can wait in the lobby or come back. We won't need you for a couple of hours."

My high hopes for this film were dashed pretty early on with the style and the acting ... both of which I thought were pretty poor. The story was clunky and it took a long time for the time-travel element to kick in ... so the first third of the movie was very slow. Riko was a bit creepy in her lusting after Soichiro. Then her waiting 10 years and then cold-sleeping was wonderfully convenient in terms of their age difference ... yawn. I also thought the rest of the main performances were pretty off-the-shelf stereotypical baddie. I had to look up an explanation of the double-Soichiro aspect of the movie ... cos that wasn't adequately explained in my opinion. Never a great sign when having to google for explanations. 44/100.

I haven't read the book, but this the screenplay is masterful. Usually with these types of films I can guess far in advance what's going to happen, but this one actually kept me guessing for a while. It was very enjoyable. The pace was great and kept the story moving. It's not too often that a good book translates into a good movie, but they did a really good job on this one. The characters were written well and also acted extremely well.

As someone who read the book in the late 1960's as a teenager and who has reread it many times over the years, I feel that the update of " The Door Into Summer" was excellently done. I have read all of Heinlein's books many tines over the last 50 years as well as many other SF and fantasy books. Heinlein's stories were never complex although they did require the reader to view things from a very different perspective. The stock ownership was the key to Soichiro and Rita's future and the revenge on his double-dealing partner and ex-girlfriend. His actions on retuning to 1995, enabled him to demolish the former company and establish a company that owned the robot patents and the patent for the plasma battery. This placed him and Rito in a future of success and happiness. The stock ownership was key all the way through the story, just as it was in the book. As someone who has multiple degrees including an MBA, and dealt with stock, bonds and contracts for 50 years, there is NO gibberish here. Heinlein would have been very pleased with the update of his story and it's successful film interpretation. WMB, BS, MD, FACC, MBA.

People always say, "The movie wasn't as good as the book." Well, this is the exception to that rule. They took a really good book and actually made it better! The original Heinlein novel had a couple flaws, and this movie fixes those flaws, while leaving all the essential elements of the story intact. The novel includes personal robots marketed in 1970, and antigravity in 2000. The movie pushes personal robots back to 1995, and gets rid of antigravity altogether. The novel has an 11-year-old Ricky in love with the 30-something protagonist (creepy) but the movie makes Riko 17 years old (not as creepy). It's a wonderful story about perseverance and hope. It's a lesson about not giving up, taught to us by the real hero of the story: a cat named Pete. This is about as close to a perfect movie as anyone could wish for. I just wish I spoke Japanese so I wouldn't need the subtitles. Spoiler alert: I thought it was a little campy to include a robot which is so humanoid that it can pass for human, in the year 2025. It's a well-worn sci-fi trope, seen everywhere from Westworld, to Austin Powers, to Battlestar Galactica. But I'll forgive this indulgence because it provides a little comedy.

I watched it in Netflix without waiting anything special from this movie. That's why I was quite surprise to discover it was really good, a solid scenario with good actors. You should give it a try !

I didn't have any great expectations for this movie, but I'd seen Alice in Borderland and thought Kento Yamazaki was pretty good so I thought I'd give it a go. I was pleasantly surprised. The plot is a tad woolly at times but the characters are really well drawn and the romance (such as it was, this has even less hand holding than your average shy boy k-drama) was quietly moving. The charisma of the movie falls entirely on Yamazaki's shoulders and he's up to the task, plus there's an adorable robot and a CAT. All boxes ticked, thank you Japan.

Good adaptation of this famous sci-fi novel, a good stepping stone for those who are interested in sci-fi, and have not read the book, (shame on you), read to book and you will see the movie with a different prospective. Enjoy.

This book is one of my favourite Heinlein stories. While not a 100% rendition of the original novel, this movie embraces the heart and soul of RAH's book. It's an amazing emotional experience to see RAH's characters brought to life and even if with the story modifications, I loved what they did with this. Top shelf and a massive THANK YOU to the honourable people who made this movie!

I've been a Heinlein fan for decades. That's not required. This is a beautifully made rendering of the book. Of course it has a Japanese vibe, and that doesn't hurt. It brilliantly captures the humor and both cat Pete and the other are spot on. Watched it subbed on Netflix.
