For the longest, I've been trying to find the Rankin-Bass special that featured and included a town called Kidville, where all its inhabitants are children and hadn't been successful. I remember catching those scenes of this special some years back on cable. It's no wonder I didn't know that they were part of this special, which I found out after watching it over a week ago on Youtube. I must've missed the title when I first saw those scenes evidently and I don't even remember ever seeing the special in full before then.
My thoughts about this special. I was going to give it the highest rating possible until I read the review by the member who gave it three stars. She made some, I guess, sensible points on why it isn't as great as most reviewers of this, and some others outside of this site, may make it out to be. The amount of stars I give it are between the lowest that have been given (or given so far) by the aforementioned female reviewer (my amount a little higher that hers) and the highest that have been given (my amount a little lower than the others). One reason I chose to give no less stars than six is because I like the Kidville concept. Another is it's great to see the mailman, S.D. Kluger, make a recurring appearance here, but there are several, other similarities that will remind viewers who have already seen the Christmas special, Santa Claus Is Comin' To Town, even right down to the title. There may be even more similarities than differences that would've set it apart more from that X-mas special. I just found out it's supposed to be a semi-sequel. In that case, I could overlook that, but then again, more sequels to originals should have more distinctions and be better. There still may be some flaws in this that I may have missed and probably never would've thought much of had the more negative reviewer not pointed them out, like how the villains attempted to stop the yellow train from reaching town and that another, better way could've been made for the villains to attempt. I presume I just have mixed feelings about it. However, I've now decided that the previous two, Rankin-Bass Easter specials are much better than this one, considering this is a semi-sequel. I don't really, completely dislike it, but simultaneously, I don't like it as much as the other two Easter specials and find them more superior. It's still nice and alright. One other thing I'll say is the religious references were a surprise.
