I think I didn't express myself clearly--it was completely unfun because it felt like I was doing nothing. There was no roll, no anticipation of maybe missing, and no challenge, thus... unfun. I LIKE difficult games, and when things go wrong. Some of the best times in games are when things go completely wrong and to me, there's just no chance of that with MM. Now, a situation of the epic proportion described directly above would have been way more epic had the wizard rolled and then hit instead of auto-hitting (but it sounded pretty epic anyway, good story, hehe).
I realize though that not many may like that level of difficulty.
