COOL effect, the stories are there, the universe is there, just make it look cool. Which is exactly what this movie seems to be doing.
The pulse effect looks fine, but beams can be interesting too. One issue with moving to pulse-based effects is that it becomes more difficult to distinguish between phasers and torpedoes. Maybe they'll depict torpedoes as trailing glowing wires back to the launch tubes as some modern torpedoes do.
