I've been re-reading your posts and found some new ways I should be looking at films, especially creativity wise. Also I may have some insight for you.
Good films provide a different kind of learning experience. You won't notice everything that a film does right, but you will notice what they do differently. Sometimes it doesn't work for you, other times it can inspire you. While shitty films shows you what not to do, you never will be inspired.
Inspiration, personally, does not have a distinct means of unsurfacing. Sure great films like Manhattan have inspired me into film making, but so has Bad News Bears (The remake) Hot Rod, and Snakes On a Plane. These by no means are Great films, but they are entertaining as hell. They have inspired me to make the most enjoyable films that I can make. As I am currently watching Iron Man, it is quickly showing me that median between Entertaining, and Great, can be achieved.
And what do you really learn on the set of a bad film? You can't learn good shots, you can decipher that by watching the film. You can't learn great directing... because it's a bad film. If there are anybody guilty of shit directing, its a vast majority of studio directors. These directors often come from technical backgrounds, and make rookie mistakes all the time. The amount of flat lines and cliched uninspired scenes are overwhelming, especially in shit studio films, especially with bad scripts. You wouldn't learn anything about pre-production or post-production, so what's left is you learn how the crew is structured, and how all the equipment works. Out of all the jobs that are required in film, managing a crew will never be one of them. I would rather cook. Seeing the different equipment would be nice, but then I again, I like cooking better than setting up lights where people tell me. Cooking is a lot of fun.

After reading Hugh Macleod's blog, I can easily see where your point of view is coming from. His post only strengthen's your reasoning and has defiantly, for the better, changed the way I should be approaching film making. Balancing "Sexy & Cash" and "A Hobby is not a Job" seem to be the perfect match for your cooking and film making career. I should also be much more aware of what I need to learn and how to execute creativity. More importantly spend more time thinking, before providing advice.
As for working on bad films....Maybe you should approach it the way you have approached directing. That in the preformances you get on a take, may not be what you want, they may even suck completely. But that one moment that does go right, is what makes it special. Once these are strung together these moments, you've got something top notch. At all moments, on any setting, you won't be learning something new, but their will always be unexpected little things that will surprise you which you can learn from. VPTurners example is a good one.
If you want to make a good name for yourself, why not do it by being the shining star inside the crap. Even if it is a shitty film, their are bound to be people to network with. They will notice your hard work and creativity. In the future,they can potentially be a huge asset.
Summary: inspiration has no specific way of unsurfacing, though their are ways to make it come through faster, and better, one shouldn't rule out every possibility. Aka I like bad films and they inspire me. After reading that blog though, I certainly must rethink how I approach creativity.
Name for yourself: This past summer I worked a shitty job. I was a flag man for a road crew and stood in the road for 8-10 hours a day. Usually doing nothing. I fucking hated it. But I did the best I could do at it. I've been told quiet a few times they want me back, best flag man they have ever had. A well known man at the head of the county is letting me use him as a reference, and just so happens to have a relative who was an editor for Pixar. Even the shit jobs help out in unexpected ways when you make a name for yourself.
