My pet peeves about transformation media in general
#1 Werewolf or were creature characters in post transformation form and stay in that form (scooby-doo's school for ghoul and hotel Transylvanian)
#2 Characters that only have transforming body parts: hands, feet, tail, ears (Princess Resurrection)
#3 Lack of creativity in cartoon and animation!
https://www.youtube.com/watch?v=BU41WngBYW0 when an flash game create better transform sequences using still images and sound effects than an very elaborate and expense cartoon than you have problems.
#4 ignoring an certain fan base! Shows and movies will cater more to people who into feet, weight gain, muscles growth,etc than furry and transform fetishes!
