As much as people bash
Unlimited, I still admire its technical design and fluid animation.
Even though it was a weird setting, they definitely got Peter's arc and melodramatic cues right. Too bad that it was Rino Romano's only tenure on the character outside of those early 2000s, pre-Raimi films video games.
I'd like to see the scripts for the unproduced episodes--he was supposed to return to Earth at some point from what I've read on various wikis.
EDIT:
Someone has looked into this by contacting the original writers, if anyone has an interest.
