Øivind Rosvold’s review published on Letterboxd :
Pretty good drama that is based on a true story. In this movie, Bale does one of his best performances that i have seen. If the real footage at the end of the movie is to go by, Bale got the real guys behavior down perfect. The boxing seems legit, abit more action'y than real boxing i guess, but it seems pretty realistic. Great actors, good writing, good story. Great movie.
