I found What Doesn't Kill You riveting because of the realistic approach taken by writer-director Brian Goodman. His interesting material is based on experience, with the script co-written by supporting actor Donnie Whalberg. The performances are great (especially the underrated Mark Ruffalo), and despite the risk of being predictable, this film encompasses much in terms of character - mainly what one is given in life either to survive or rise above. Blu-ray extras (which may be the same as the dvd) include a commentary, deleted scenes and making-of featurette. This is a good example of what lower budget independent filmmaking can do with the right combination of talent.
