Because the director sucked?
Seriously, J. J. Abrams has absolutely no sense of distance.
Explosion visible from another planet unaided.
Planet is a quarter of the way across the galaxy.

Not to mention how the doom laser even got there. It's clearly slower than light, since, well, we can see it move. We don't see it go into a portal or into hyperspace or anything. How does it cross interstellar distances?
If he can't be bothered to do some basic research on what he's filming (space is big), that probably says something about his approach to directing.
jj abrams is a moron and i agree with you entirely but
how many people watching the movie actually noticed? the average moviegoer isn't that bright, to be honest. i doubt most people would realize how long that beam would take to hit, not to mention the fact that it wouldn't be visible from distant systems
