Are the blasters supposed to be lasers or some kind of launcher of hot plasma beam-bullets? Lasers are invisible and nobody is swinging a light saber to block a light-speed anything... and even if they did we wouldn't see it because it's invisible and traveling at the speed of light... so if the jedi knight sees the laser being fired with his time freezing eyeballs he still needs to swing his sword arm faster than the speed of light to interdict the light-speed laser beam with his light-saber.... but since we can see the jedi knight flipping and cartwheeling and swinging saber to interdict a stray blaster laser beam then said jedi must not be moving fast enough (faster than light) to intersect the laser beam... therefore none of this makes sense. or does it make sense because the blaster is really hot plasma that travels in perfectly straight lines.
there I go, now I've ruined Star Wars.
