I don't honestly know where the line between Humorous Anger and True Anger is when I think about idiot parents letting their kids not discover the real Dr. Seuss before inevitably watching those shit films with friends. As I mentioned I can kind of understand non-kids liking, maybe, one of the Seuss movies but that's mostly because they know Seuss and, most likely, grew up with him. But to introduce little developing brains to the empty-headed schlock that are the Seuss movies? If anyone does that then they haven’t actually thought about what Dr. Seuss' work really means, or at least, not as an adult.
Read a couple short essays about him by other authors, many great ones found in Your Favorite Seuss.
Rediscover your favorite books or animated specials and see how they strike you now, as an adult. Any work of fiction changes over time because we change as well, certain aspects about our character have fallen away while others remained or have expanded.
It's like how the same work of fiction can mean various things to separate individuals. People sometimes have changed enough at various points in life that when revisiting favorite works they view them in new ways or discover things previously unnoticed.
We react to the world as we continue to experience it, in doing this we form opinions, reevaluate beliefs and, hopefully, continue to grow and mentally evolve as a human being. No, seriously, I am talking about human beings. From Earth. Stop laughing.
Anyway, after reading real Seuss, sit down and watch the contrived, advertising vehicles that are the movies. Need I say this again? THEY HAD THE LORAX ADVERTISING FOR MAZDA! If that alone doesn’t smack you in the face and make you realize that they missed everything that the The Lorax was about, then I don’t know what could. I mean, did you even read that book? Maybe I take this too personally, but not without good reason.
