Flipped through to get a quick peek and will 100% recommend Daytripper. Have read some of these and have several others on my to read list or have copies waiting for me to get to. I'll have to give this list a good read over later, I'm sure I will be adding more things to my to read list!
I've been reading Saga as the trades came out (although I got the deluxe book for the first few). I started reading it right after my daughter was born, which doubtless helps, but the whole thing is brilliant.
I re-read the list last night and it really is a solid list. It left out a lot of stuff that I would think of, but when I think about it, I read a lot of guy oriented comics even if I don't read a lot of cape comics. This list here on the other hand is very well balanced. There's pretty much something in it for everyone.
I've had The Watchmen (of course) sitting at home for like two years. I need to just commit to it some time.
You should, if only to see what people talk about when they talk about the comic. Just know that it gets talked up a lot, but it does have some flaws, so don't expect to be blown away. I think it's one of those products of pop culture where the idea and influence of the thing became greater than the thing itself.
