I really don't like QTE's, they tend to come across as lazy. Sure you could argue that it's just pushing buttons same as regular gameplay, but it sure as hell doesn't feel the same. Space Marine, a good brawler with fairly well flowing combat fell completely flat at the end by having a QTE bossfight. That and the never realized sequel hook at the end left a bit bad taste in the mouth despite most of it having been really good.
"Press these buttons to watch a prettily scripted animation" is perhaps ok in some games, but not in most action packed games that I've seen them in. Or can someone honestly say they enjoyed the boss"fights" in Far Cry 3?
I'm willing to buy them working in something like Walking Dead (never played it) because they sound like they're different games by nature. Maybe QTE-ish things work in some games. But if a game is built on some well realized action mechanic, be it shooting or chainsword swinging, adding QTE's is simply very jarring. They even, dare I say it, rob me of my immersion.
And lest we forget: Thief, Deus Ex and Half-Life never had QTE's
Actually, I guess I should mention one game that sorta made QTE's work. Just Cause 2, one of those newfangled GTA-likes. You could steal civilian cars as you normally can in that genre, but stealing manned police/military vehicles forced you to do a three button QTE. It added a certain sense of struggle to what is usually a fairly brainless exercise and I can't say it was horribly done. I'm not sure if it ultimately added anything, but if there's a way for action games to incorporate QTE's, that's maybe the route to take.
