Luv'ed it. Great animated film. Smart, funny, well paced and you learn a bit about history. Great for adults and children. Based on the 1950's cartoon and a wonderful remake and that is very hard to do.
The movie is doing very well due to mainly word of mouth and there being not that much competition and it is a good movie. The Groods and How to Train Your Dragon were also released in the same time period and it seems the first week of March is a great spot for an animated film release.
