I think a large part of splitting up "ages" also come down to personal eras. For instance, Morrison's New X-Men and Brubakers X-Men are part of what most would consider the modern age. But for me, X-Men is split in pre-House Of M, and post-House of M, and I can't group them together. Or Claremont/Post-Claremont. As a 90's teen reader, there's three different ways I group that time. Early 90's Marvel, when I first started reading comics, the Image era right in the middle, and then my college years when I became more writer focused and flashy art no longer impressed me. All one age to most, but personally, it was like my own Golden/Silver/Modern Age. It's impossible to group Infinity Gauntlet, Youngblood, and Preacher all into one group.
Keeping on topic, I read the Deadpool Minibus. Lot of fun. The first three minis are all one story. Deadpool Vs Deadpool was probably my favorite. This book is a perfect example of the silly, irreverent Deadpool that's popular with the mainstream, non-comic fans. Extremely violent, if that matters. Good art and colors that work well oversized. If I had to compare it to movies, I'd say entertaining, mindless summer blockbuster based on a clever idea.
