I agree Cal. The significance, atmosphere and moment(s) are what the WM1 and WM3 main events will most be remembered for more so than match quality.
I need to re-watch LT/Bam Bam and Taker/Sid.
One thing to watch out for with Taker/Sid is the fucking length of the match. I still consider it to be "good" but man, they could have taken 10 minutes off it and they would have still gotten everything in
