Good concept, poorly executed.

The acting in this movie is really good.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

what a terribly boring film. I'm sorry but this is absolutely not deserving of best picture and will be forgotten quickly. Entertaining and engaging cinema? No. Nothing performances with flat faces and mistaking silence for subtlety.
