Speed Racer (2008). I re-watch this every couple of years with the kids and absolutely love every second of it.
The final race sequence, especially the last few minutes after he re-starts his car is close to perfection. Few sequences in film get me so emotional as Speed finally discovers his true potential. Inspirational clips from earlier in the film run through his head, the commentators squeel in adoration, and the whole sequence builds to a huge crecsendo.
Rating aren't great on IMDB or Rotten Tomatos, but I feel like many are missing the whole point of the film. It's an absolute over the top, light hearted blast. I don't think there are many better family flicks out there!
