Disney animation is top notch, and unlike most non-Pixar films, Tangled is fun and enjoyable (Pixar's Lasseter Exec. Produced which may explain the difference).
The "Sampson" twist on Rapunzel's locks is a neat update and the two animal characters kept my kids (9, 7, 2) in stitches. Rapunzel and Flynn have great (if predictable) rapport, but songs were on the weak side (hence the 4-stars). An exception was the ballad duet (guess who sings it)...
