8. 'Teenage Mutant Ninja Turtles: Out of the Shadows'
The 2014 Teenage Mutant Ninja Turtles reboot surprised some industry analysts by becoming a genuine hit, grossing nearly $500 million. Money like that means a sequel is an absolute guarantee, and sure enough less than two years later, we were given another one. This time around, the Ninja Turtles battle not just Shredder, but also Bebop and Rocksteady. Yawn. Haven't we seen this many, many times before? It grossed less than half of the first one, but still pulled a profit. The actors all signed on for three movies, so it's quite possible we're all going to do this again come 2018.
