That's too bad, really. And I'm not being sarcastic. He should keep on producing them.
You guys are missing the demograph here. I have a 5-year-old kid and she has quite a collection of those 'crappy sequels'. She loves every single one of them and would actually have repeated viewings. Sad to say, guys, the 'crappy sequels' are not intended for you.
As is this Tinkerbell movie. Hard for you teens-and-beyond to imagine, my daughter, a big fan of Peter Pan, is an even bigger fan of Tinkerbell. I am sure as heck that she'll drag me to watch this, regardless of the criticisms levelled on it by the adult critics.
Another example: no sane adult would watch any of the Barbie movies from beginning to end. My 5-year-old kid watched them all. And watched them again.
So, before you shoot down this movie and label it as crap, just ask yourself if this movie was intended for you in the first place.
