It's well acted, well shot and the score is excellent but it's very confused as a historical account of early 19th century boxing.

The fight between Belcher and Pearce would not have been fought with gloves, nor would it have had timed rounds. It would have been fought under London prize ring rules since it was about 60 years away from the Marquis of Queensbury changing the game.

Not sure why it has such a low score from the critics compared to the popcorn audience. I enjoyed it. Found it believable. Maybe it's too real. Making a champion is simple. But the simplest things can be difficult. And boring to watch perhaps. Perhaps it's just a little too British? Especially the ending. If you love sports biographies, it's worth a watch.
