The goofiness of Revenge mode aside, I remember thinking WM XIX was pretty decent, especially considering how disappointing WM X8 was. The HIAC matches were, I think, the most accurate and fun version that any WWE game has featured, yet, although I didn't play last year's SD vs. RAW, but they haven't changed their HIAC in years.
But, as it's already been established, Revenge Mode can be fun in the so bad, it's good way. And as you complete missions, you unlock stages for use in regular matches, which can be fun for a change, particularly when you have multi-man matches where you win by throwing each opponent off of the platforms and into the ocean, as seen in the above videos.
Here's another good Revenge mode Youtube video...
