8. Transformers
Unlike many of the entries on this list, Transformers has a less revered source material. Based off a toy, but remembered thanks to a much loved eighties cartoon, Transformers fans can be some of the most passionate around. Which undoubtedly makes it difficult for them when their beloved franchise became some of the most sexualised, muddled films in recent memory. Unlike thoughtfully adapting a comic book for love of the sourece, a film based on a toy will always have money in its headlights. And even with Steven Spielberg attached as Executive Producer, it was soon clear Transformers wouldn't buck expectations; Dreamworks tried incessantly hard to get Michael Bay on to direct. Why they would even consider that we dont know. When Bay was brought on, he couldn't bear putting his name on a stupid toy movie, so instead turned it into a stupid toy movie, with guns and boobs. But in adding those teenage driven subjects, Bay managed to cull most of the mythology and innate, untempered coolness that fans of the series loved. Transformers initially became a franchise in favour of G.I. Joe due to the formers potential association with the Iraq war, but with Bays additions, there ended up being little face saved.
