Seems like Sir Schmoopy would like some constructive criticism. Very well, I'll offer you some since most others don't seem to be catching on as to what exactly that is.
The graphical complaints in the intro are possibly warranted because it looked a bit blocky during the busy parts, especially with so many characters on screen. I'm not sure if there's a way to rectify it or not, so if you can't, don't worry too much about it. After all, it's not like you can remake that entire intro perfectly without messing too much up.
On to the story elements: My biggest complaint is throwing away James, Stevenson, and the Arbiter. They looked like good characters and possibly candidates for a second party, but now they've been tossed into who-knows-where. A good way to turn this unfortunate pickle into an unexpected gold mine would be, of course, to make them fall safely near a few other characters, possibly soulless ones, and have them adjust to those bodies. We naturally don't have to worry about following their plotline until they join up with Schmoopy's group, and even then, it can be explained shortly in a single episode. And for simplicity's sake, let's just say that the people that James, Stevenson, and the Arbiter end up inhabiting are either soulless, totally fine with someone inhabiting their bodies, or they weren't pissed in jars. Either way, it's good to follow up on.
If you were planning to kill off any of these characters, like James, you could say that their jars didn't land safely. I still think that one of them should land safely, though. It's a good crop of characters to choose from, so you can pick your personal favorite and have him be the sole survivor if you have to.
As for whose body they inhabit, I still suggest an undead cleric. I don't know why, but such an oxymoron sounds more than fitting. It's a joke in itself, since he can't really turn undead without killing himself, regardless of how powerful his iteration of that spell is. As for the explanation why he was never accidentally turned in Cleric Private School, he was going to visit his relatives in their tombs way out east or something like that. You'd be better at explaining this than I would, since you're making the series.
Anyhow, that's enough commentary from me. Looking forward to more Unforgotten Realms.
