Don't get me wrong, I have a ton of Sideshow figures, but, even taking into consideration the "every figure can't be made" and the "you can always come up with a why didn't they make _____" arguments, Sideshow = incomplete.
They make who they feel are the "core" of a line and thats it. I understand that some lines don't sell as well as others but when you think about it, how many Sideshow lines are complete?
Planet of the Apes - no Aldo, no TV versions, no Ape-o-nauts
Highlander - no Kurgan
Get Smart - no 99, no Hymie
Hogan's Heroes - no Kinch, no LeBeau, no Newkirk, no Carter
Buffy - no Anya, no Caleb, no Dawn
Angel - no Doyle
Universal Monsters - no Dr. Frankenstein, no Ygor, no Maleva....
Terminator 2 - no John
X Files - no Lone Gunman, no Reyes
Hellboy - no Rasputin, no Liz, no Dr. "Broom", no Myers
This Island Earth - no Exeter, no Cal, no Ruth
Twilight Zone - no Rod Serling, no fill in the _____
Outer Limits - no fill in the _____
These are just off the top of my head and from lines I followed. I'm sure there's more and that other characters could be viewed as missed.
From X-Files, I'd rather have Mr. X before Reyes.
Angel should've done Doyle or Wesley before Lorne.
I really wanted Trent from "Demon with a Glass Hand" from The Outer Limits.
