9. Bubo (Clash of the Titans)
Why They Derailed The Movie: Clumsy & Charmlessly Annoying Sidekick The original
Clash of the Titans movie is a good one, up until the point where we're introduced to a "great" new character presumably designed to win the hearts of adults and children alike, but only ever really succeeds in annoying the absolute sh*t out of everybody for the remainder of the movie. That's to say, once Bubo the mechanical owl has turned up to aid our protagonists, it's all downhill. Who comes up with stuff like this? Well, Greek mythology does, apparently, since Bubo was supposed to be Athena's pet owl, except here he's mechanical for some reason (it was the '80s). And although a loveable owl sidekick should have captured our hearts and imaginations, Bubo only ever comes across as a clumsy wannabe R2-D2 - let's just say the world wasn't quite as enamoured with the idea of a "bleeping" owl as the filmmakers probably thought they would be.
