This movie is very interesting. You get into it thinking its going to be a slapstick comedy because of Wilson and Galifinakis. Then it turns into almost a sad mental illness drama. Then starts to get good. The thing I believe many people dont see is the reality of the mental illness. Yes the drugs do change you that much. You become what society believes you should be by the chemical compounds. They actually stopped giving lithium to patients because of the adverse reactions and suicide. But all of that aside, it was a great interpretation. Hopefully it gives new insight on life for some, while for others it will probably blow over their heads because of ignorance. The ending was strange though. Only reason I gave it 4 stars. Hope this helps someone decide seeing all these 1 and 5 star reviews.
