Okay, despite the fact that I understand the lack of Samoa Joe love, this angle that TNA is running isn't his fault, so I don't really get the Joe hatred that this thread seems to have become. This isn't a Orton vs Samoa Joe in general thread (at least not based on what I read) but just about the angles.
WWE's angle is more intense, more fueled, whereas Joe just seems to be meh in terms of intensity. He's not feuding with Book, so why go after Sharmel? She was just wrong place wrong time. To me, it actually lessens the Joe character in this instance more, irregardless of whether we see it or not, because it is a woman who was just in the way and now she needs to be "punished." So basically what you have is a fat Samoan assaulting a helpless woman.
With Orton, his moves were calculated. People are supposed to hate Randy, and therefore his abuse of Stephanie adds fuel to that fire because people like her, either because she has big tits or because she's married to Trips, or both. It moves all characters along. With Joe, you look at it and go "Okay, he's carrying a helpless woman, who just happened to be there, wrong place, wrong time, to the back." It's not planned, it's not a strategy. It's a spur of the moment reation, which basically screams "Yeah, I'll beat a woman. What?" What does assaulting the wife of one guy in a group that your feuding with do for the angle? Not much, in my opinion. Is it going to make Scott Steiner pissed off? No. Kurt Angle? Not quite. It doesn't really do anything but piss off Book.
Adding the abduction of Sharmel to the MEM/Joe angle does nothing. Starting the RKO/Trips run with an assault on Stephanie McMahon was brilliant.
And besides, Joe only walked out of the arena with her because Spike won't allow any male/female violence on Impact.
