Alright, so these events might not be looked at anymore, but I'm still very much interested in knowing what went down during that time span between Infinite Crisis and Final Crisis. I've read IC a few years back, didn't like it so much, save for the fight between Superman(s) and Superboy/man Prime. Now I'd really like to look into Final Crisis, and I'm aware that Countdown comes after 52 and One Year Later. I suppose I'll worry about Countdown when the time comes.
What's the best method of reading 52 and One Year Later? Are there specific collected editions?
