I'm pretty sure Townsend was Leo, not Mike, in the original TMNT toon.
Also, Rob was the best part ... though I did enjoy Pa sounding like a bad Rowlf. Matt was pretty good, too.
I think I know what mainly weirds me out, besides the VA's and the sense that not a lot of effort went into writing ... the Rock seemed so empty. In the toon, they could show FR and the Gorg's garden what it would probably look like without the muppet-version forced perspective. The Garden, especially, seems way more spacious -- but it would to us, who are incredibly small. However, muppet FR is chock full of Fraggles, Doozers, weird creatures, etc. Animated FR (at least the ep that's on youtube) ... seems almost vacant by comparison. I understand it'd be a pain to draw all the inhabitants ... but ... still...
