What?...
Man, that was lame. It would have been better if you poked fun at Wolverine being Canadian, how it seems he can never die, or perhaps how no matter what you do with XMEN, Wolverine will always be the coolest and most bad ass :P Well over 100 years old, ages slowly, heals fast, has an indestructible skeleton as well as those claws, doesn't take shit from anybody, does whatever he damn well pleases, sometimes acts like a savage, spent lots of time in Japan, etc.
There's LOTS of material you could toy around with to make a good comedy whilst not offending some fans of this particular super hero. A little research could go a long way. Not like my little review means anything, you got 4.25/5 so clearly lots of people really like this flash. With a bit of home work, it could have appealed to more people resulting in a bigger score, ya know?
