Well, I've seen the movie and I think you're spot on. It does the job. It's not the best but.. it does the job. And the short run time helps. I'm not talking shit- I rather enjoyed it. The problem lies within the industry- there are so many bad ones it makes anything decent well worthwhile. But, hey, I like that :)

I have never understood why people like that kind of things, I truly prefer it when it is like subtext but one needs for all the tastes.

This is another result of the same problem, I believe. People can't always be scared, so they've started to confuse being uncomfortable with being scared. This reflects on the filmmakers, because it's easier to make something uncomfortable than it is scary. Cause and effect, I guess.
