As for
Neverland and
Zagreus, I sort of understand what you mean. However, on a whole for someone who was needing a Doctor Who "fix" at the time I purchased them (before the new series, wasn't it?) I really enjoyed them. I made sure to go back and read up on a few of the previous stories so that I understood what was going on with Charlie. But, even if I hadn't the stories made it explicitly clear. Over and over again.
Personally, I wished all the old Docs had played their Doctor's rather than a back-handed way of doing a multi-Doctor story. I'm sure it was done to give the actors something new to play. But, come on...you've got them all together! So, that was a bit of a tease. And don't get me started on the "jealous" TARDIS. The Pertwee "cameo" was awesome...and somewhat haunting, fittingly. Enjoyed the Alice In Wonderland motif, and the Brothers Grimm-
ish nature of the Zagreus concept/rhyme. Charlie was overly whiney in Zagreus, though. By the end I was really hoping she would die.
Also, I liked how it briefly touched on romanticism with the character of The Doctor, which I know was later shrugged off with his "alien ways". Loved Leela, Romana, and the two K-9's. Where's Andred throughout all of this? Rassilon was a-w-e-some. Loved Colin as the vampire. TOTALLY pictured it. Syl as the Disney-esque guy came off weird, though. Kind of pervy, almost.
And, my favorite bit of the whole story? Colin remarking about his regeneration "a bump on the head??"
In the end, I liked
Neverland far more than
Zagreus. But, I could detect the weakness in both.
