Das Boot!
I actually remember a debate over whether Wrestlemania 20 was too long. I didn't have a huge problem with it at the time, because it was quite a stacked show, but I wonder if I'd still think the same if I watched it back now. I definitely don't think it should become the norm. There was a lot of stuff on this year's Wrestlemania which really didn't need to be there. Removing some of those matches and segments would not only have shortened the show, but also improved the quality.
