Okay, so I didn't pre-select this group of sci-fi movies for reviews. It was more that I had a lot of movies still to review and many of them happened to be sci-fi. And since sci-fi is my first love as far as genres go, unsurprisingly I've kept checking out new sci-fi movies since then. So here's the latest one I've come across...
Oddly titled "Shadow Walkers" in the UK. A title which has absolutely no relevance to the film's content whatsoever. "+1" is a science-fiction film about a group of older teenagers/young adults most of whom are home for the summer after their first year at uni. The party seems to be set up by an absurdly wealthy friend and while this is rather taken for granted, it does at least explain the size of the house in which the events unfold.
A strange comet causes a doppelganger of everyone at the party to appear. Initially no one at the party notices because the partygoers are led to an event outside while the doppelgangers repeat their actions inside.
