it seems to me that there is a fine line between acceptable and non-acceptable, and it all depends on the gamer on how bad they think that bug/glitch is... but personally i think that if a script don't work and you get stuck in a game, thats a bad one... and for that I'm gonna have to blame game testers for not finding them to tell the programmer about them.
I remember the Max Paine one, not that was a really bad one !!! Imagine all the people who bought the game and didnt have the internet, since the internet was not that big as it was today... bet they were so pissed
luckily i had the internet
