Essential Avengers, Vol. 1

I think this held up better than Golden Age Batman. I enjoyed it, though it's still kitschy of course, with plenty of unintentional hilarity. (Like how after Zemo sprays the city with super adhesive glue, the Wasp goes to find “Paste-Pot Pete” to save the day. Thank God for Paste-Pot Pete!) It is a LOT of comics and my interest waned toward the end–but maybe that's just because Iron Man and the Wasp both left the team halfway through. (Also the Hulk and Ant-Man, but I care less about them.)
