15 Good Horror Films That Totally Lost It By The End

The Film:

Danny Boyle's hugely accomplished science-fiction film, which follows a spaceship crew as they try to reignite the dying sun.

The Ending:

This shouldn't be here, since technically it's not actually a horror film. Unfortunately it resembles one - a very bad one at that - by the end and this is arguably the epitome of a promising film ruined by a terrible plot twist.

The two thirds are excellent, before the character of Pinbacker shows up. This is the only time when the always-brilliant Mark Strong appearing in a movie has been a bad thing. Pinbacker is the insane captain of the first ship which went out to try and revive the sun and the first mission's only survivor. He quickly emerges as a crazy slasher villain who starts attacking all of the surviving crew-members.

The film now descends into an immature and weak slasher film in space and not only is it a lot sillier than what came before, it's also a lot less scary. SThe final third of Sunshine is, putting it kindly, pretty bloody awful.

Danny Boyle and Alex Garland are two very talented people, so it's hard to know what possessed them to derail their own movie so badly. Maybe they were trying to pay tribute to Alien or something like that. If they were, they created a movie that, for the first 2 thirds is up there with Alien, but the final third more resembles Alien Covenant.
