QTEs aren't inherently bad. The quality depends on the craftsmen. They can enrich games with emotionally charged moments the game wouldn’t have otherwise. I've played games where they felt sooooo damn good. Like finishing off a boss or enemy in spectacular fashion and you just want to jump up and say "aaaaaaggggggggggggggggg!!!! yeaaaaaaaaaaaaaaaaaa$#^#$@!!!!!!"
I actually didn't mind the force unleashed ones. They are optional but if you choose to do them you get an extra bonus of XP or health, much like God of War's finishers. Splinter Cell's mark and execute is optional too, and I saw a video where the developer missed so it's not completely automatic.
Arkham Asylum was one of my favorite games last year and I like how they masked the QTEs. During fights a little indicator would flash when you needed to counter but it didn't directly say you needed to push a button, you just knew what it meant.
Fahrenheit's context sensitive stuff was actually pretty cool. Instead of just pressing A to open doors you hold down A and pull the stick back to simulate pulling the door and other stuff like that. Interestingly Fahrenheit also had some of the worst QTEs too later on. Long and instant death.
