I'd be lying if I said that I didn't enjoy some of what DotM had to offer. I personaly love the mechtech weapons and would be excited if Hasbro released them in blind bags or something. The Cyberverse stuff was great (Blackout, Powerglide, Hatchet, and Guzzle are all winners) and I really like the more simplified transformation of the figures.
Some of my favorites from the line are the deluxe seeker mold and voyager Skyhammer. And the Human Alliance basics are all great IMO. I can't get enough of them.
