Ha.. funny you mention that TiM because I've really wanted to see something like that too.. Back in the 70s and 80s those could be made and shown in Grindhouses.. Today those theatres don't really exist anymore so we have lost them in the process.. I would also like to see a revival of those films..
Exploitation films should definitely be revived. I would not only love to see horror movies like those, but some great Kung Fu movies and even those old "pimp like" blaxploitation films.
I really would love to someday (of course if I make it rich it will help greatly) open up a grindhouse and just show exploitation films from the old days, and if revived now.
