Funny you posted this considering not only is Hogan one of my all-time LEAST favorite wrestlers(only one i can't stand more than him[who was actually a wrestler and not comedy relief] is Bob Backlund!!! Annoying & Boring Cooke!!!
Anyways.... but Prior to his TNA arrival, around the time Angle jumped ship to TNA I became a big TNA fan. Always loved Kurt Angle, they had great young talent, I thought that the six sided ring was AWESOME! and in an era where WWE was becoming very PG TNA offered that more edgy and physical wrestling any 90's guy like me loves from the attitude era. I bought shirts, dvd's, hell I even sat almost front row at BFG cause I had never been to a live TNA event. In a nut shell, I had basically become almost a bigger TNA fan for awhile. And one thing killed it ALL for me!!! HULK HOGAN!!!
The second I saw he had joined up with TNA it went all down the toilet from there. I knew when I heard he had been given the "golden key" to the place it would kill TNA.....and I WAS RIGHT! No more 6-sided ring!!! They turn Angle from there Biggest star into a jobber and give him ridiclous story lines like the Jarrett-Angle thing. They mis-use the good young talent(remember when Hogan said Bobby Roode wasn't ready to be champ? I DO!) and throw crap down our throats like Crimson(Red hair, was pushed way too fast? ring a bell?) and worst of all they thought it would help them so they trusted him and brought back all these old talent that no one cared about(Flair, Foley, Bischoff, etc.). Since that time Sting also had his worst gimmick possibly to date and everything that the Hardy Boyz have gone through since being there is just sad. Hogan just sucked the life out of that whole place in my eyes.
It has seem to have gotten slightly better since he has been off air but he did his damage and I think sadley enough, TNA went from being edgey competition for WWE that could have sparked a 2nd Mon-Nite Wars too midget wrestling or any other terrible show endorsed by Hogan.
