Right away from the very start this is very gripping. The performances are truly excellent, not just Bale, Adams and Wahlberg, but the entire cast. The script seems very realistic and the exploits of the characters are emotionally moving, grimly funny and always fascinating.
This is a proper powerhouse of sporting drama - with more emphasis on the drama. The boxing scenes are fun, but nothing close to something like Raging Bull or Rocky. That's really my one criticism - the story of Ward's boxing career is pretty unremarkable, until his epic trilogy with Arturo Gatti, which is not featured. Also, the underdog narrative is very tired and boxing fans know that Ward's "big shot at the title" never really happened the way it's presented (he never won a legitimate world title, despite being a real warrior). So that detracted from the overall quality of the film, for me, being a big boxing fan.
The audio-visual quality of the Blu-ray is very good, the picture is very crisp, sharp and consistent, the sound very effective. Overall this is a really good film and Blu-ray, well worth buying.
