I'll start with what's great: Archie comics continues to pump out the classics, without screwing up the color! You basically get the most pristine reproductions you could ask for, on nice glossy paper, at the right size! This is also an excellent sampling of the various eras, after the last two installments offered somewhat questionable selections overall.
The not-so-great: there is still nothing comprehensive about these, they feel like at best they could someday add up to a solid twenty book survey of Archie history, but realistically this company has been more focused on hooking fans with a steady drip of content rather than offering comprehensive archive. I dislike the way giant volume numbers are slapped on the spine, especially since they allow each volume to drop out of print pretty quickly. Oh, and they tend to use the last quarter of these books more as promotional tools. But still, a good classic Archie fix.
