    Simply amazing

    I'm a huge fan of the novel and I was a bit skeptical after reading some negative reviews from acclaimed "critics". After the first 20 minutes of the movie I realized that sci-fi adaptations have a chance...in Japan. Hollywood lost it and I no longer waiting for any good adaptations from them. But Japan is a totally different story, they pleased my heart and soul with this adaptation, truly perfect. They changed some things to fit the story but I like these changes, organic and logical. People who think that the movie is boring should watch another crappy Hollywood adaptation, for the rest of us I hope Japan will deliver more good movies.

    Live on a re-written future!

    Many movies revolve around romance and time travel, and this one is following that genre. The first 30 minutes actually was quite interesting, but somehow it went downhill after that. Lack of tension and also maybe lack of villains, perhaps?!

    The difficulty of making a good movie with all the known outcomes is the lack of suspense. The scriptwriters should know that, the director too, but this movie was allowed just to roll by after it's all been figured out in just the first 60 minutes. Even a twist at the end of the film doesn't help much.

    Mediocre 6/10.

    Favorite book

    The Door into Summer has been a favorite book of mine for many years. When I found out they had done an adaptation, I've been waiting for it to come to the USA. It did not disappoint. I do recognize that if you haven't read the book, you may be confused. And key plots were changed to fit into a 2 hour story. But I loved that they pulled dialogue straight from the book. Loved that Pete the cat's greatest moment was in the film. If you're a Heinlein fan, I definitely recommend it.

    Heinlein revisited

    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.

    It says "Enter"

    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.
