I know there were misgivings by a lot of Trekkers about this movie,and I'm sure some of them might not like the direction it went in, but for me, I think this movie was first of all very accessible to both Trekkers and people unfamiliar with the Star Trek universe. It was a much-needed infusion of new blood, away from spin-offs and the same-old-same-old. I particularly thought the castings was genius, even if liberties were taken. Acting was superb. CGI - amazing and yet not overwhelming with explosions and action sequences. A nice balance between action and interpersonal scenes. The tone was uplifting and positive without being wholesome and stupid. I really like what they've done with Spock, although many might not agree.
When I went to see this movie with a friend who is a big Speed Racer fan, I felt that even if the plot was weak, at least the visuals would be enough to carry it.
Well, I was right about the visuals. You felt you were in there with the racing, your heart in your mouth. For Speed Racer fans, this is a fantastic tribute to the anime, with references to different incarnations of the shows, cars from different episodes, anime itself, and even the original and English versions of the theme song.
The plot was slim but enough to satisfy, with some wonderful exposition on the state of the brother, Rex. The youngest brother, Spridle wound up being less annoying than I feared, and he carried some of the scenes with great humor.
I'd definitely recommend this film to racing fans, Speed Racer fans, CGI fans - pretty anyone unless they hate action and loud, fast thrills.
