Oh yeah! I was watching it when it first aired as the shorts during commercial breaks on CN. I thoroughly enjoyed it then, and it was great finally being watching it on DVD (I'd watched it through a couple of times on YouTube as well). It's the closest thing that we'll get to the comics, sadly.
I totally agree with you on the comparison/contrast with Renegades. Still to date, Renegades has been the new show I've enjoyed the most on the Hub, but I was surprised tonight just how much I like both after having watched Resolute. They're both so excellent for their own reasons.
Dude Resolute was awesome, the fandom seems to prefer everything new, so a lot of folks who liked it now claim they hate it and that Renegades is better. Resolute wins, I like both for different reasons and the sad thing is, it's probably the ONLY mature GI Joe cartoon we will ever get.
