Not wanting to go off on a tangent on previous post. Just making a Python-ish commentary on failures that seemed to work despite the ability of the transporter system at the time to overcome the situation.
The basic premise of the transporter, as well as impulse or warp drive never changed for the worse from one episode to the next in TOS, was expanded upon in TNG, (warp scale changed, for one) but in my opinion, there was an established protocol for transporter capabilities that was ignored in nu-Trek. How about that Amanda could have been hit by debris before transporter took hold? That would have worked and added to the drama. Otherwise the transporter should not have even been "man-rated" as NASA would put it. The whole system seemed too slow and randomly faulted. Checkov should have had a real mental and script dilemma feeling responsible for loosing Amanda, another point that could have added some emotional tension to the crew make-up. Spock could have had it in for Checkov which would have been overcome by a "logical" assessment of the situation that they ALL have to work together to save the ship and universe.
