It's What's Inside had preceded my expectations when I had viewed it. I had heard of the movie beforehand but wasn't sure what the main premise of the film was, so I decided to go in blind.
I thoroughly enjoyed it, and it's become my favorite film that's come out in the past 3 years. I love the eerie tension, mood and the acting was extremely well done. I found that there was so much depth within the characters and overall story which had me wondering what I would do in the given situation.
I'd highly recommend this for people who are looking to watch something that requires their attention and those who love mystery.
The only critique I have would be how confusing it can be since it was tough (at least for me) to remember the character names and who had switched over to what. However, that's not to say it was bad since it seems like that was the direction the film makers were going. It urges viewers to watch a second time to not only understand the motives of the characters better but to see who had switched and in what way the ending twist had effected the movie.
I typically never write reviews but in recent time where most movies have become an overbaked idea or unoriginal (which I understand it can be hard to create your own idea since the wide range of filmography) this film had gotten an idea and put a really interesting twist on it.
Anyway that's all I wanted to say, really good :)
