Tangled I actually enjoyed, but I do understand that it's fashionable now to dump on anything Disney produces away from the Pixar brand.
I don't think Tangled is up there with the best of the studio's efforts, but it certainly was an improvement from things like Princess & the Frog, Home on the Range, Treasure Planet, Hunchback of Notre Dame, and many, many more.
Personally I have exact oppisite feelings of "Tangled" and "PRincess and the Frog". "Tangled" was okay. I thought the bar scene and the palace horse were very good.
However, I think "Princess and the Frog" was better partly because of the fresh return of traditional animation and partly the characters were a bit stronger. And I agree with Jerry that some of the songs were a bit more memorable than in "Tangled" (I did like "Mother Knows Best", though).
