The only genre I have any problem with is musicals, but that's just my own tastes it's nothing to do with the films.
There's no way you can shoot low-budget stuff on lots of locations. It's just a practicality thing because every time you move, it costs time and money.
You really have to be careful with the clues you lay into the film - if they're too heavy-handed, or you've pandered to a slightly stupider audience, then you've spoiled it for the people who are even slightly smart.
The things that inspire people to think are what keeps a film alive.
If you judge everything by how photographically real it looks, then you're missing out on a lot of what art is about and what communication is. There are ambiguities in life, and that should be reflected in art, cinema, and storytelling, I think.
