Just watched +1 (2013) which is a pretty cool movie with an awesome concept that kept my attention locked, but ultimately is a bit under-baked.
First...this is a Sci-Fi film, not Horror (though it does have a few Horror elements and is a bit Twilight Zone-esque). It seems like the only place this is getting any attention is on Horror websites, so I'll discuss it here.
Here's the deal...David visits his girlfriend Jill at her fencing competition, but then allows himself to be kissed by the girl who just beat her in the tournament. Jill sees this and dumps him. David spends the rest of the film trying to win her back while insanity unfolds around him.
The first problem is that you're then supposed to sympathize with David and root for him as he tries to win back Jill...but I was on her side of the argument, and got even more so as the film progressed and his tactics get more manipulative and darker. However, he is never presented as anything but the sympathetic hero trying to win back his girlfriend.
So, there's this massive party. Both Jill and David are there, separately, and David brings his horny friend Teddy who just wants to get laid...and lucky him...his dream girl is there!
Then the concept kicks in. After most of the party moves outside, a meteor crashes. The lead characters realize that somehow, there are now doubles of everyone, doing exactly what they were doing 20 minutes ago! David uses the knowledge he has of the last several minutes to try to win back his girlfriend's duplicate. The stakes are raised as the two parties get closer to meeting face to face.
As I said, this movie is quite entertaining from start to finish. However, while David is unlikable, the film barely even touches on something far more interesting...social outcast Allison. She fits in nowhere and seems to identify with no one...and now she has an exact duplicate of herself. This story is glossed over in passing, and likely should have been the emotional center of the film. As presented, her character is not defined enough to leave an impact. The issue with the massive party possibly meeting up was also more interesting than creepy David, who mostly avoids the conflict to chase his duplicate girlfriend around. Unfortunately, the film focuses on his story and leaves the rest of the characters as background filler, though even with that they carry more emotional punch than his character. I would have rather have seen how the events impacted Teddy's dream girl (who appears to be deeper than just a party skank, but that isn't explored at all)...or any number of the other characters who get only a moment of screen time. OR, had they actually addressed David's scheming ways it could have been interesting.
I actually do recommend this movie, it is fun to watch. However, I came away feeling like there were a lot of missed opportunities to make a really great film. It COULD have been one of my favorite movies of the year, had they not made some rather stupid decisions on story elements. I still liked it, but feel like I was robbed of the emotion that the set-up promised.
