I just watched this film for the first time and while it was enjoyable enough, what's up with the brotherly rivalry between Wolverine and Sabertooth going unresolved? For two hours, they built it up as this big showdown that would go down at the end with one of them (Sabertooth, obviously) dying, but then they team up against Wade and then part ways and that's it?! It'd be OK if it was resolved in a latter film, but I just saw the cast for the Wolverine film (which I haven't watched yet) and nowhere is Sabertooth/Liev Schreiber listed anywhere. Disappointing. Also, on another note, after watching this film, William Stryker's death from X-2 is kind of disappointing. This film kind of makes you wish Wolverine had gutted him personally, but I guess that's a whole separate topic.
