I have those same feelings and fears about the series coming up Brian... I worry it's not gonna live up to my expectations much the way E1 was a flop when compared to the classic trilogy's quality overall.
My love of the toons is unending though, they were done well. Especially if you were able to watch them with that feeling they were stories being retold with exagerration and things, but based in the truth (if that makes sense). They were just great fun and excitement then...
I remember watching every episode when it premeered and getting all anxious waiting for it to come on... It was fantastic. Everything from the goofy Separatist General in the trenches to the fast-paced action of Grievious stealing Palpatine... There was just a ton of great stuff int here.
Even the episodes that stood alone (not my favorites) were still great... The Quarren/Mon Cal episode with Fisto was really nice even though it didn't tie to anything... And the Windu bit where he gives his cloak away like the old Steelers Coke commercial from the 70's. That stuff's classic to me.
I just really hope the new series is able to match that quality. It's a lot to live up to in my eyes.
Same as I hope the live action TV show is able to parallel the great way that Episode III was done. If it was done half as well as say Deep Space 9 or The Next Generation (the last half of the series anyway) I'd say it's got legs to be a hit itself.
