Just echoing other opinions about the lightsabers.
I think the problem with the ROTS lightsabers isn't so much the colour, but the very different look they have at times. They are a little bit too vibrant and solid at times - perhaps I am just too used to OT, I don't know. But in the OT, you could see they were like a powered laser, and not like a straight line solid, pointy, object like in the ROTS. I guess it seems weird because they seem almost too perfect.
