Bob, I hate to disagree with you (I do, in fact, agree with you very often, and I usually see where you're coming from if I don't), but re: Chocolate, were we watching the same movie? I just watched it a couple nights ago, and I can't see where all this outrage at the premise comes from. I didn't even need subtitles to see that Zen is autistic, not retarded, and there is a big difference. She's probably not quite up to what we would consider average intelligence, but she should nevertheless probably be classed as a "high-functioning" autistic (the term "high-functioning" has no official definition, but is usually used to refer to cases in which autism is not accompanied by mental retardation).
Furthermore, the "ultimate opponent" you tout is someone she takes down in about a minute. Sure, at first she isn't ready for his spastic capoeira twitchiness, but as soon as she has a moment to see his patterns, she adapts and takes him down in five seconds flat. Her ultimate opponent, if she can be said to have one, is far more realistically a six-foot-tall skilled martial artist whose name we never even learn because to his boss he's just an enforcer, but who Zen can't defeat until she tricks him into leaving himself vulnerable in the middle of a jump.
Seriously, MovieBob, watch that movie again. It's got all of the good points you talked about, but every bad point you mentioned is completely spurious. Chocolate is in every bit as questionable taste as Rain Man. (Not to say it doesn't have bad points at all, of course. The lack of budget for sets is one problem, particularly since all of the hospital scenes, for three very different types of visits (birth, diagnosing Zen as autistic, cancer treatments) are all filmed in the same room.)
(For a more detailed analysis, you can see my blog post [http://whollycrapproductions.wordpress.com/2011/10/14/chocolate-review/], but just watching the film with my comments in mind should be enough.)
That said, I agree that all of the movies you mentioned that I've seen are great fun, and I hope to have a chance to see the rest! I've specifically been trying to see Buckaroo Banzai for years.
