For me, this was one of the most solid RiffTrax ever. I can't remember a time I laughed so hard and consistently. Perhaps it was the fact that we had to stop half-way through. I used to have the belief that the guys would always run outta steam towards the end, but now I really believe I run outta steam.
I've come to the same conclusion. I've found that I usually enjoy the last half of the trax more when I break them up over two or three nights. Especially the really long ones. And I quite enjoyed the X2 riff as well.
