John Cena is, without doubt, one of the most controversial figures in the WWE. His character has an enormous fanbase, but it also has an army of detractors.
Whether it's his "5 Moves of Doom" or his apparent refusal to put over new talent, there's plenty to annoy fans about Cena's character. The most infuriating aspect of his persona, though, is that it has not changed in any perceivable way over the years.
For many, the obvious answer to this problem is a heel turn.
Unfortunately, the process of turning John Cena into a villain is not quite as easy as it would be for any other Superstar. He occupies a unique position in the WWE landscape, so any heel turn needs to be considered carefully.
