I think the X.F.L was all about the way it was given to you. It was rushed, it was sloppy and that's why it failed. Plain and simple. I've had this conversation with several people in the past, and the basis of what I've come to is this..
Original American Football, the A.F.L/N.F.L wasn't broadcast on television to start with. It was tried out in front of live audiences and tested several times, in multiple markets to see whether or not it'd be a big hit or a bust. It naturally grew on fans, and obviously as we all know became a huge money making sport.
On the flip side to this coin, Vince McMahon (like he always does) seen something that made a lot of money.. and wanted to make money off it, by making his own version only - with his special way of touching it. So instead of testing it out by running a year or two, silently without major television exposure (minus ESPN/local news stations picking up small reports on attendance) McMahon decided the old philosophy of "Anything you can do, I can do better". And he ran with his brand of Football - believing it'd survive and make it, on the pure assumption that it'd take part during the Off-Season of regular N.F.L Football, right around the time people would be left wanting more.
The X.F.L didn't fail because of anything more than the pure fact it wasn't test-ran on audiences, first. And McMahon could've saved a lot of money by doing what in the back of his head, he knew he should've done to begin with. (Think about it, W.W.F ran house shows long before televised shows, to make sure people loved it.)
As for the alternative nature of the Sport, it was everything it said it'd be.. Extreme. It wasn't the N.F.L, but McMahon wanted you to think it was so close to it, that sooner or later he'd attempt an overthrowing of the N.F.L. (which I firmly think in his own crazy, warped mind, he wanted to attempt years down the road if this worked.)
The X.F.L wasn't "Professional" to the terms of the players are the most elite. The sights, sounds and all around "atmosphere" isn't the same as the N.F.L, and wasn't suppose to be, but in a ways WAS meant to be. Because it was created, in the original mind-set that you'd tune in to get your Football fix by watching something very similar, yet more edgier, slightly more extreme and rough.. after the N.F.L season concluded.
So.. my final thoughts on the X.F.L.. it was Wrestling based and never had the opportunity to survive, because McMahon knows Wrestling.. not Football. He had Wrestling announcer's commentating, in which only Jim Ross truly had Football commentating experience. Fuck, is Lawler even a Football fan? I've only ever seen him go on about the Indians. (baseball) He had pyro and a huge entrance set-up for them to enter, a lot flashier than that of what normal N.F.L players entered to (off camera, most the time, mind you.)
So no, the X.F.L got bashed because it deserved to be bashed. I liked the logos, I liked some of the looks. I liked the concept. But it was rushed, hurried and overall shoved down our throats before we could even attempt "sampling" or "tasting" it to see if we'd like to try a full-course of it.
