For me, the guy was at his peak during his first two years or so. I thought that maybe it's just some weird kind of nostalgia, but even watching the episodes side-by-side I still find his earlier ones a lot funnier. I'm not even sure what it is the newer ones are missing. Not that his newer episodes are terrible or anything, but the earlier ones like Silver Surfer and Die Hard had me in stitches.
I'm curious of the movie, at the very least. I honestly don't look forward to the game review itself because honestly, what can you even say about E.T.? It's an Atari game, almost all those games were just one stage over and over. The "special effects" episodes he had for AVGN were often the worst ones IMO, so I'm not sure I'd like it if the whole movie turns out to be like that.
