The First Purge is by far the weakest of the four movies of the franchise and it’s not even close. Weak plot and thinly written characters torpedoed a series that was on a decline and for myself, I’m pretty much done.
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. It’s nothing memorable yet it’s probably worth a Red Box rental rather than a blind buy.
