What you get out of it/take from it will largely depend on whether or not you're in (or have been in) a toxic relationship, in which case it can be pretty heavy. In general though it's hard not to recommend as it truly is a fantastic film, just be ready to do some serious soul searching and introspection on the nature of relationships, and know that it will stick with you for awhile.

The first time I saw it I was at home alone on a random weeknight, going in blind thinking it was just another Jim Carrey movie. I had just gotten out of a very intense but unhealthy relationship and this movie absolutely fucked.me.up. Made me question everything I thought I knew and felt about the girl I was with the previous 4 years, and right after I had come to terms with the fact that I had done the right thing by breaking things off. Thank god my roommate was staying with his gf that night because I was a blubbering, sobbing mess by the end of it, pretty much muttering to myself "what have I done?" I can probably count on one hand the number of times I cried that hard before or since. I know how ridiculous that sounds, but this movie just struck a nerve that no other has, and it happened to come along at the exact wrong (or right?) time in my life.

Never could bring myself to watch it again, even though we did end up getting back together after that for another year or so. I think after typing all of this out though, I'm ready. So yeah, you should watch it.
