8. Halo: Reach (2010)
It's always an obvious risk releasing prequel when you already know what's going to happen.

Unbelievably, that's not the best part. The following clip shows was happens after the end credits. It's one last hurrah for Noble Six followed by a fitting message of appreciation for your valiant efforts.
