My favorite two issues were Hawkeye and All-New Wolverine. The others were interesting and enjoyable, but I didn't feel as invested in those characters. That's the great thing about comics, though--there's something for everyone. If you're undecided on what comics to read, try a few of the Generations issues to see if anything intrigues you.
