Bolt is exactly like 101 Dalmations II, which features a dog named "Thunderbolt" who is the main character of a tv show and believes the tv show is real. One day he gets out and is confused because he believed the fake world of the tv show was real. Basically, Disney just took the story of their direct-to-DVD sequel, knocked "Thunder" off of the main character's name, and re-sold the movie out. I did like Bolt, it had some good original characters like Rhino and Mittens, and the animation was amazing, I just don't like the unoriginal story.
Tangled, though, is awful. Seemed very un-Disney to me, and definitely shouldn't be considered a classic with such classics like Snow White and the Seven Dwarfs, Cinderella, and all those. I felt the same about Princess and the Frog, though I'm starting to actually like that one, because at least it has better music than Tangled and tries in some areas to seem like a classic.
