When the majority of the game's showing is QTE's then expect a lot of them. The common sense is that what you see is probably what you're going to get, the reaction isn't surprising.
The game'll probably be decent to pretty good since it's Insomniac, but I was also disappointed in what I saw. I didn't expect Arkham plus QTE's from the developers behind Sunset Overdrive. It doesn't look that much different from Beenox games aside from graphics.
It was L I T E R A L L Y less than a minute of the showing, how exactly is that the majority again?
