Despite the horrible current booking there really has been a lot of great OMG moments. For me i got a few.
First time seeing the Canadian Destroyer: I had never seen anything like it, I mean in WWE at the time the most extreme move you had was Shane's Leap of Faith, and the most devastating Piledriver was the tombstone. Then I watch TNA and see a guy do a frontflip piledriver, and the guy who i believe was Mikey Batts, sold it so perfectly I thought he was dead.
Bound for Glory 2005 Monster Ball: Two moments, of course the obvious one being Jeff Hardy's amazing dive, however the bigger OMG moment for me was the Rhino Driver on Hardy to end the match. Idk i guess something about piledrivers shock the hell outta me but a piledriver from the second rope is ridiculous, and the way Hardy landed, words cant describe so here is a vid, its at 2:52-2:55[YOUTUBE]http://www.youtube.com/watch?v=zoWJNt8SGg8[/YOUTUBE]
Elix Skipper: Walking across a 20 foot cage and hurricanrana'ing a guy from the top of said cage. Nuff Said.
Unbreakable 2005 Main Event: OMG as in wow that was one of the greatest matches I've ever seen. Probably TNA's greatest match ever.
Ultimate X Matches from 2003-2006: The LAX vs. Styles and Daniels was the last good match IMO but all of them had ridiculous highspots and are just insane.
Daniels almost breaking his neck at BFG 2009: Falling from the top of the structure in Ultimate X and landing on his head truely left me speechless.
Angle's Backflip Headbutt from this years Lockdown: Moonsault my ass, that was the most extreme headbutt in wrestling history. Angle's still got it man and that was probably the last time I've had an OMG moment with TNA recently.
Chris Candido's Death: Shocked the hell outta me, I loved the push he along with the Naturals were getting and they were a great trio and he elevated them much like a guy like Teddy Long did with Rodney Mack in 2003. Sucks cause once he died the Naturals never got what they could have.
AJ's Frontflip in Ultimate X: [YOUTUBE]http://www.youtube.com/watch?v=8OluLdOIbaQ[/YOUTUBE] I really don't know how to describe how this shocked the hell outta me, it is in no way the biggest bump in TNA history but still it was crazy
I'm sure im forgetting quite a few but those come to mind
