Possible reason why Kylo Ren's Lightsaber looks as it does
There was a whole lot of fanboy disgust at the design of Kylo Ren's lightsaber with the crossguard beams. From what I remember many felt it was designed to look badass and thus ignore the traditional Jedi lightsaber look for some wow factor.
But during the movie there was a big deal made over Luke's lightsaber. Why? A lightsaber is just like any other - there is no power associated with the lightsaber like if it was Excalibur.
Then watching the saber duels with Kylo Ren's lightsaber kind of made me realize that Ren's lightsaber beam is kind of crackling and seems to have a electrical short in how the blade flares? and those crossguards maybe are not there to serve as crossguards?- they look like excess energy venting exhaust ports?
What could be going on with all that that we should be taking away as a viewer? To me it indicates Ren's lightsaber is badly made. Like the ability to make lightsabers has become almost a lost art when the Jedis were wiped out. The lightsaber is venting energy because it is a primitive design - kind of reminds me of the smoke belching from a coal fired steam engine compared to the clean function of a modern electric motor in a Tesla.
This is why Luke's lightsaber would be prised by Ren - it is an example of a functioning lightsaber technology lost to him and not so much a relic that he needs to possess like Excalibur.
Does anyone know if Abrams or anyone else elaborated on the reasoning behind the Ren saber design to confirm or disprove my theory?
