You know, I'm not actually looking forward to it one bit. I'd much rather they kept the EU and made some movies based off that, like the Thrawn Trilogy. I've read some leaked info and the movie seems...bad. It compromises some very important things about the lore, in my opinion. And it keeps pushing the "two separate sides of the force" approach which I think is a load of bantha...faecal matter.
Also, from a technical point of view, that lightsaber is absolutely ridiculous. I do like the CGI on it, but aside from that it's rather stupid. I like to think I know a bit about lightsabers so hear me out

Now, I didn't know this, but Tabaet pointed out to me that when lightsaber blades collide, their magnetic field locks them in place there. They can't slide. So already, the crossguard is a bit pointless. But let's assume that they retconned that too. Let's say the blade is sliding down the sith's blade. What does it hit? The protruding emitter. Not the lightsaber crossguard. It hits the emitter. It cuts the emitter off. Along with several fingers I'd imagine. Pointless, just pointless I tell you.
One thing I did like was the shot with the X-Wings. That looked pretty cool. But I won't be seeing the movie. Or at least, I won't be paying to see it. I choose to believe that the EU still exists!
