And the stun setting in TOS was using a pulse, not a beam. Not to mention the phaser pulses in "Balance of Terror."
There is precedent in prior Trek for most of what people complain about in the new film.
If I remember right, the stun setting in TOS wasn't always a pulse, they had some beams too. The phasers used in BOT were ship mounted versions completely different than the hand units. Actually, one could make the case that the Enterprise had early pulse phasers before the Defiant got them in DS9.
There is precedent for some of what people complain about in the new film, but not all of it.
