Really good watch, would watch again, and can recommend, especially for slasher fans.

As soon as I saw "trapped in a movie", I was sold. I'm a big fan of survivalist situations (realistic or not), and have been waiting to find a "trapped in a movie", as opposed to "trapped in a video game" for some time now.

While my expectations were a bit high, I think the cast helped even me out some. This has some highly recognizable cast for 2015:
Thomas Middleditch "Silicone Valley"
Malin Akerman "Watchmen"
Adam Devine "Pitch Perfect"
Alia Shawkat "Arrested Development"
Chloe Bridges "Pretty Little Liars"

Most of which I'm not actually a big fan, but Taissa Farmiga ended up carrying most of the movie anyways.

Given that they're trapped in a slasher movie, we have to deal with several cliches, and SO MUCH meta discussion that is literally takes over the movie at certain point, but that is part of the survival strategies. We also get some pretty interesting death scenes, along with some that are more comedic than interesting.

Surprisingly, the movie is actually both too formulaic and unique to discuss much without spoilers, so I'll just say any slasher fan that enjoys discussion about slasher movies is going to like this one.
