Late to the party here, but got a Avengers Pro NIB a couple of months ago and am seeing a number of these "Avengers sucks!!!" posts online. I understand people have different preferences and tastes and whatnot, but there appears to be some real vitriol for the Avengers pin, which baffles me a bit. It's almost as if people are personally offended by AVG, that it's not just that they don't like it but that the machine SUCKS SOOOO BAD. Oookay.
My family and I have now played somewhere around a couple hundred games on our Avengers Pro, and we like the pin very much, an opinion I personally grew into. When I first started playing, I thought the play was okay but wasn't overly thrilled about it - I had the same opinion as some in this thread, where it didn't feel like it had any flow and the rules weren't particularly novel or interesting. But as I got more and more games under my belt, I started to appreciate the difficulty of the shots, which require skill but not ridiculous amounts thereof to make. It's the difficulty of the shots which makes them all the more satisfying to hit and chain together as you ramp up your skills. I also began to understand the depth of the playfield and the strategy required for setting up various heroes, the versus modes, and the multiballs. Once you get into the groove with hitting the hero shots, and understanding how various shots set up modes and multipliers, Avengers becomes an incredible thrill, and that's when your score progresses exponentially. If you don't put much time into the game, I can understand why you would be underwhelmed, but you'd be selling the game short to think that that's all there was to it.
I can understand why people would have preferred the original voice actors provide voice samples for the game, but it doesn't bother me, personally - I thought the actors did a fine job voicing their respective characters, and the Hulk, who does the vast majority of the talking in the game, anyway, is hilarious. I also like the music and how each character has their own theme which comes to the fore when you active their mini-game.
As for build quality, I haven't had any complaints, perhaps because mine is a later model where Stern presumably has already worked out some hardware and software kinks. I have no problems with my Black Widow ramp, haven't had any parts break or show undue wear in the admittedly short amount of time I've owned it, etc. The tesseract plate did get a bit loose over the first 20 games, such that the plate would sometimes tilt under the ball's weight, trapping the ball, but I tightened up the post attaching the cube to the base plate, and it's been fine since. Oh, and I did install the Pinball Refinery's tesseract mod recently, because, well, the lighted cube is terribly cool. 
Anyway, I just wanted to put my thoughts out there, since the loudest people commenting on the Avengers pin seem to be those who want to crucify the game, and I don't want people coming in fresh to think that's it's some kind of open and shut case. There are people who don't like the Avengers, which is their prerogative, but there are also people out there, like myself, who really like the game and think it's a solid pin and great fun to play.
