300 is a movie that I never really immensely enjoyed back when it was released and even today, found it to be great to look at, but little emotion behind the amazing visuals, though some of the fight scenes were pretty bad-ass.
The Purge had an interesting concept but the closer you look, the dumber it was. But if you set the logical aside, and can handle an unlikeable and utterly stupid family, the suspense and thrills are effective and at 85-minutes it’s not a big time investment.
