It's a short movie. The fighting sucks which it kinda shows most of it. It's been that way ever since the frieza and the last movie before that.

@FreestyleArt I get where you're coming from on the fighting, it's really over the top with less emphasis on choreography and strategy. However, seeing as though Broly is essentially a savage that never properly learned how to fight, it makes sense that it'd be a straight up slugging match.
