The season 1 intro is awesome. And man, what a nostalgia blast seeing it again. I think I remember liking the show when I was younger.
The 4th season felt so tacked on cause of it... Still decent, but, the show clearly had its run, only to be like "oh, nope, we're not done yet." Though, at least they made the rest good despite the show technically ending already.
What I find more surprising for me is that the only 2 I watched out of the list you posted were the ones I left in the quote above. I think some of it is cause I either didn't have Cartoon Network on the channel list when I was a kid, or I just didn't watch it. I seem to remember gravitating towards Teletoon and Family Channel more than YTV and Cartoon Network.
However, I do remember Courage the Cowardly Dog and Megas XLR, and both of those were fantastic, the latter especially. Megas still sticks with me today, and it may have been what spawned my love of mecha.
I also remember catching a couple episodes of Storm Hawks at my neighbour's place. Didn't think much of it back then, but looking at it now... Can I say how much I dig the aesthetic? It looks great. Maybe less the character animations, but I am super into the ship and world design.
Come to think of it, while this thread exists... Anyone remember Chaotic or Spider Riders?
