Well, there’s obviously the canon (Alien/s, Star Wars, et al), and then there are the ones with cannons (Riddick, Mad Max, etc), but these are not necessarily my own favourites, or the ones that made me laugh, or cheer, or sob into my popcorn, or that have simply stayed with me.
5) Donnie Darko – yes, we’re veering into noir fantasy here, but this has that sci-fi staple of time travel, a rabbit from the future, schizophrenia, and the end of the world too. And love. And a very dark heart.
3) E.T. the Extra-Terrestrial – because Steven Spielberg has never been sweeter and neither has an alien.
