Oh God. No. Please no. I finished the original series. And it was so tough to do.
If they have to do it, if they ABSOLUTELY have to, please reset all the power levels somehow for any returning characters in episode 1 and KEEP THINGS CONSISTENT. I.E. If you give a character time-stopping powers, there's no way the bad guy gets away in the end of season 1, right? C'mon now. Best to avoid that type of scenario entirely. Give the characters powers that aren't overly powerful and can be used in combination to tackle a stronger threat.
Also, make sure there is some sort of goal driving the action and the characters motivations forward. That show had more downtime than anything. Sock-stealing idiot characters.
Because they'll read this post. Right?
