I'm currently making my way through Infinity Gauntlet. So far, not impressed, but things seem to be picking up. I'm 2 issues in, and my impression so far is that it's about 20 pages of boring shit and exposition that seems to be explaining shit that happened in some other book, followed by 4 pages of Thanos being fucking awesome. If we can increase the ratio of Thanos being awesome to boring shit, I'm going to be happy.
I often hear people citing this as a favorite, though. If it's a favorite of yours, what did you enjoy? It seems like the badass Thanos moments and the Perez art are the main selling points of the book.
