I consider it the most overrated steel coaster out there. For such a large innovative ride it seems to fail to do certain things that should be pretty textbook for a ride of its tech level.
Now, it's an amazing machine. The positives on it are nuts and the fact that it can manage to pound you with such high magnitude force for such a sustained period of time is impressive. I mean, the thing needs water sprayers in the station to keep the wheels from melting for crying out loud! However, it's not my cup of tea because it spends so much time doing stuff I don't really find interesting and not enough time doing stuff that I actually enjoy. It's not that I hate positives, there are several coasters out there that can really pound you with force that I enjoy, but for other aspects of the ride. Skyrush, Banshee, and others are all great examples of this. But personally, when such a large amount of the ride is dedicated to chilling out in the same turn forever as it exerts the same magnitude of force on you and very little is done to break it up, that's not going to impress me. Now, it does have the best drop of any giga in the US and there are a few moments where I feel it utilizes its speed well (that "right turn, unbank, rebank, right turn" moment is incredible) but it's going to take more than the same mildly amusing transition over and over again to really win me over on a ride like that. Now they made an attempt to do that with a few air hills around the layout but they flat out fail to get you out of your seat. They legit feel like the missed air hills on the second half of New Texas Giant, or any overrated "classic" wooden coaster that barely gets you out of your seat, such as Screamin' Eagle or Kennywood's Racer. It's definitely a positive-focused ride, probably moreso than many other coasters out there. Not so much the magnitude, but the focus it puts on the force over all else is probably why it has this rap.
As for the magnitude of the positives, they're powerful. Not the most powerful I've experienced (that's gotta go to SFMM's Goliath) but still powerful. I don't grey/black out much but the first turn got my vision a little spotty, and when I first rode it as a new enthusiast (opening season as Intrimidator) I was seeing in muted color for a bit after I got off. If you're a positives guy you'll go nuts for it, but if you're more about speed/airtime/agility, it's nothing special.
