Yes, 'cause a blue/green lightsaber and a blue/green lightsaber alone would be all it would take to make a bad guy indistinquishable from a good guy. Things like body language, vocal inflection, general attitude and the actions they partake in – those things don’t matter once goddamn iota.
Oh, but I forgot – only little children under the age of five watch SW movies.
[JEDIT]
Oh, this guy is just oh so warm, friendly, and inviting,
At least he’s wearing black armor and not white robes like what’s-his-name suggested.
EDIT: I’ve to come to a conclusion. The only way Episode 7 (discounting Episodes 8 and 9, which crazy potential for originality) can be completely original is if it is set a lot more than 30 years after Return of the Jedi. Would you want to sacrifice characters like Kylo Ren and seeing Luke again for a more original story that is not guarenteed to be better?
