I was watching this film with a friend of mine. He was a really big fan of Doraemon when he was a youth in China, and he had spent the last few weeks introducing me to the series. I'm not a very big fan of anime, but the cartoons reminded me a lot of the cartoons I used to watch when I was younger, so I found myself enjoying them, on their own goofy level. I watched the movie on his suggestion.
The plot concerns Nobita and his friends attempting to stop an invasion of Earth by an alien robot army being spearheaded by a young woman and an electronic bowling ball they met earlier. I wouldn't say it's the most original concept, but it fits very well into the Doraemon universe, and it's well-written and well-directed enough to keep you invested.
The thing that struck me the most about this movie was it's somewhat darker, more emotional tone, compared to the TV show. Without giving away the plot, I can say that it is not quite the goofy joke-fest that the TV series was, although it still leaves you feeling good at the end.
The animation is quite good. It's not the best I've seen, but everything is quite nice to look at. The copy I was watching was Japanese with English subtitles, so I can't really comment on the quality of the voice acting, although I can't say anything seemed wrong with it.
Overall, I would say that I thoroughly enjoyed this movie. It's not anything that I would call 'innovative', but that's not a bad thing. It's simple, but comforting, like chicken noodle soup. Anybody who has a little under two hours to spare and wants to enjoy something pleasant should seek this film out, especially if they are young children, or fans of the Doraemon cartoons.
(For the record, this movie was a remake of a film from 1987. I haven't seen that version, but I've been told that the animation is of lower quality, and the story is a touch different(some say better).)
Quick warning for parents: There is one point in the film where one of the female characters appears without any clothes on. She is rendered with Barbie Doll Anatomy, though, so there isn't really anything to shield your kid's eyes from. Keep in mind that this is not uncommon in Japanese animated works, even ones intended for children.
