The NY Times recommends 28 Days Later. I throw my hands up into the air, and beseech the all-powerful committees of Hollywood. I ask for intelligent tragedies and horrors, not films that start out brightly, and become harrowing only because the characters make poor choices. I want to see our best actions undone by cruel chance, evil plans, or plain old complexity.
The bad thing is that I assume there is a definite marketing reason for this. There's probably a bunch of marketing research, indicating that my advocated plot elements do not play as well as the current elements. Cursory google'ing found GoZing which pays you PayPal cash for each movie trailer you watch and review (fill out survey). I presume that similar research is done for the movies themselves.
Jeremy Rifkin's The Age of Access contends that increasingly we pay for our entertainment, that our recreational activities are tending to revolve around commercial experiences. The GoZing site makes me wonder if one could construct the reverse, where we are paid for our entertainment. This would probably require a malleable notion of entertainment. ;)
