I dont care for Tom Cruise but I love Domnhall Gleeson and that is why I gave this movie a chance. I dont usually try drug related movies because I dont like scary stuff. This was a good surprise. Not my favorite movie ever, but definitely a really good surprise and worth watching. The trailer doesnt do it justice as to the content. It plays like an interesting American History lesson. It's not scary and it even has a bit of good humor. Recommended.
