I meant on the whole. I haven't seen all the films after Pixar, but some of them like Toy Story, Wall-E, Finding Nemo, Up and Monsters Inc. were brilliant. I haven't seen Cars, so I don't have an answer for that. Not each one of the old ones was great either. For instance, I didn't reaaly like Snow White or Pinocchio-well, I generally didn't like Pinocchio. But the last years, they are making films which aim to everyone and deal with serious issues, like Wall-E, so I think they deserve equal focus.
About Lion King-Hamlet, what Book Jumper said.
Now that you reminded me of Hercules...as a greek, I know the original myth and no one can deny that they Disney film had very little to do with it. But I can't say that it wasn't an enjoyable film.
