I'd call it "suspension of disbelief." When I criticized the HBK/JBL "slave" angle from earlier this year, it's because there was too large of a gap needed to suspend my disbelief. HBK, broke? Pish-posh.
The Triple H/Randy Orton WM runup was decent. It made sense - go after my family, go after my wife, and I'll

ing kill you. Then the WM ruined the angle because (1) it was a boring match, (2) it had the distinct dishonor of going on after HBK/UT, and (3) Triple H restraining himself from killing Orton made really destroyed the plausibility of the angle for me. Yes, yes, the belt is important - but I don't believe that even a chucklehead egomaniac like Triple H would hold off of injuring someone beyond comprehension if they attacked my family and wife.
But there is good room for suspension of disbelief in TNA - at least with regard to Kip James' begging for work, and Shane Douglas' wanting one last shot at fame/glory. I also think that's why The Beautiful People work so well as a tandem - not because they're hot (there's enough of that in pro wrestling as is), but because you

ing know bitches just like that, you

ing hate bitches just like that, and you want to see them killed. Metaphorically, mind you.
And Steiner is amazing in his role - you know he really feels it when he cuts a promo on "Fat ass" Samoa Joe. It's entirely, entirely, entirely plausible. Look at Joe as a person; what would you say to him if you really, genuinely, believably wanted to get under his skin? Steiner does just that (in a TV-14 appropriate manner

).
I can't believe I just praised TNA for its plausibility in storylines - but, hey, I just did it.
