The Three Mile Island fight with Victor has impaling, crashing through windows, and a pure visceral animalistic nature to it. It's one of the few moments in X-Men Origins: Wolverine that is exactly what people claim they want to see from a Wolverine movie, but of course because of the movie it's in, it automatically gets discarded and proclaimed "bad".
In terms of myself, the idea that the hate is simply because of the film it exists in is pure nonsense. I hated it because the choreography was stifled by oddly vacillating between misguided slow motion and real time with almost every chronological cut, stripping it off any tension whatsoever. The super sanitary nature of the fight also contributed to its ineptitude.
