Overall, not a bad film. Not the best Disney animated film, but I would say it's better than the other non-Pixar, computer-animated films.
This film has a lot to like as well as a lot left to be desired. The story is a classic Disney princess tale and follows the same pattern as previous Disney princess films, which is good. The characters are engaging and the comedic moments add up to a lot of fun. On the flip-side, the film would have faired better as a non-musical. The songs in the film were random, unnecessary, and, at times, a bit too ridiculous. Like previous Disney films, the music is meant to add to the film and build the emotion of a character or scene. The music did not do this in Tangled; it almost seemed thrown in there just to make it a musical or to use Mandy Moore's talent.
Also, I think we've been quite spoiled by Pixar and their amazing animation skills. The animation in this just doesn't match the quality and believability that Pixar and DreamWorks have achieved in their films (especially with fire and water effects).
Also, I saw a lot of other Disney movies incorporated in this one, as if they took a bunch of previous Disney animated films and cut them together into one: The mother-daughter relationship as well as the daughter's wish to leave the tower for a day is almost exactly replicate of The Hunchback of Notre Dame (Quasi and Rapunzel even sing a similar-themed song about going outside). The almost-kiss scene in the boat on the lake was scene-stealing from The Little Mermaid without the singing fish. And - without going into great detail - the sacrifice and miracle at the end of the film was copied almost straight from Beauty and the Beast, from wound down to the tear drop.
Okay, I'm done ranting. Not a bad flick.
