Sorry for not reading all the posts above, but I have this to say about phasers: 1- there was a phaser shot in IV. Kirk soldered a dook knob with a phaser. Chekov broke his and it was funny. Poor stupid Chekov. 2- In a certain episode of TOS, Scotty uses a phaser as a blowtorch to cut a wall and unlock a door. in TOS-remastered, they put a visible beam there. That was the most unnecessary thing I ever saw in the world of film and remasters. I hate that.
