Against all odds, the last two installments were great.
This third one isn’t bad either—just cheesier, campier, and thoroughly middling.
You basically have to suspend your disbelief for the full two hours… and yet, somehow, it’s still fun.
That’s the inexplicable charm of this wildly popular little niche of a franchise: it’s stupid, it’s over-the-top, it makes no sense—and I still enjoy it ;-)
