It is a film you need to see. I believe most of us can relate to Fleck. Joaquin just deserved the Oscar. I have seen many reviews where it is ridiculed and criticized but hear me out. Every person relates to a thing very differently, and I believe the critics like A.O. Smith are shallow and loquacious hypocrites so do not listen to them. Todd Phillips really carved a masterpiece in this film. I believe if you've really undertaken much pain in your life you would be very relieved and would let go of it after watching this film. Joaquin portrays this very dark character flawlessly and with utmost devotion. And this is one of the reasons why you should watch it.
