Boring villains that don't deserve to be in the stories they inhabit

[Spike Spiegel]

Have you ever felt like rage-quitting when reading a story or watching a movie because the villains are boring, terrible, or just not all that compelling?

The following characters spring to mind for me:

Majin Buu (Dragon Ball Z)
Venom (Spider-Man 3)
The Penguin (The Batman)
Whiplash and Justin Hammer (Iron Man 2)
Control Freak (Teen Titans)
Hulk (The Ultimates)
The Joker (Suicide Squad)
Dracula (Blade Trinity)
Harry Mudd and Sybok (Star Trek)
Floronic Man (Batman and Harley Quinn)
Tetsuo (Akira)
God (The Bible)
Dr. Doom (Fantastic Four--not always boring, but it depends on who writes him)
Walker (TMNT III)
Magneto (X-Men comics circa the late '90s to early '00s--again, it depends on who writes him)
