Jackman isn't the problem. He looks the part(besides being too tall), can act, and seems to genuinely care about the character. The problem(s) are:
1.Both scripts failed. None of the other characters were interesting besides Schreiber's portrayal of Sabretooth(underrated) in Origins.
2.Films aren't nearly violent enough.
3.Casts are weak. Where was Ken Wantanabe?
I'd also like to note that both films trailers looked promising. Both films fell flat.
