Eh... its for little kids... whatever. Let them have and enjoy it, atleast they might grow up into cool things like robots rather than lame boring generic nowadays commercial tv and music.
On a side note, I still have hopes for a more adult TF series (not that "Prime" doesn't appeal to me), and any reasoning against it doesn't really work since there are so many levels for other fictional shows, like batman, Wolverine, etc etc. (who also sell toys) No reason why there wouldn't be a hope for it in the future. Just gota have more fans mention they want it, then theres a target audience.
A second side note; been rewatching a bit of G1 season 2 lately, and its actually pretty awesome (as in I like it more than I remembered), haha. Its got enough cool stuff going on with hilarious dialogue, I'm really digging it after so long.
