Oh, nevermind, I found it.
Was browsing through on-demand choices the other day and saw the trailer for "Area 51" which is about a group of friends who sneak into Area 51 yadda yadda. Brought to mind the other one but couldn't remember the name.
Though "AA" got horrible reviews, in my experience I really enjoy movies critics really hate. Think it's because they're reviewing things from the point of view of film school people where a great movie is "Casablanca" and so they don't review things from the pov of a fan of the particular genre so much as a more general cinema review.
