Well there were quite a few...
1. The opening shot of the crowd in Hammerstein just going apeshit
2. "This is Extreme" coming on and Joey Styles coming down to the ring, and getting choked up, and the first "oh my god" of the night. Just amazing.
3. Jericho coming out as Lionheart
4. The awesome match/spots from the Awesome/Tanaka match
5. The lights going out and Sabu showing up pointing to the sky.
6. Heyman's awesome promo on WWE
7. The whole Dreamer/Sandman vs Dudley's match from the opening intro's to the clusterfuck at the end. It just felt right. Hearing Enter Sandman(the real song) and Sandman coming out and the crowd singing along, was just awesome.
Overall, I've honestly watched this show 3 or 4 times the whole way through. It felt right, It felt like ECW, and it made for the first time in many many many years proud to be a wrestling fan again.
