I guess Red Dawn.
I wanted to see Prometheus, but I've sort of lost interest after seeing the reviews... which, by the way, seem to point out the very flaws I fear, and have seen, in many modern movies. I may watch it when it's a rental or something, but the enthusiasm is gone.
I'm not sure I want to watch anything modern anymore, as I just end up feeling depressed in the end. Even felt that way with Avatar on a second viewing.
