Dont get me started on the startrek reboot movies.
How much red matter does the vulcan science council send with spock? pretty much enough to cause widespread genocide across the flipping quadrant. How much does he need to do the job assigned? a small syringe full. what, did they think he might need to try a few million times or something? I dont care how "cool" it looks. It is illogical to send that much, and thus not in line with the vulcan science council.
That's not even considering the absurdity of the plot.
clearly, the star going nova is several hundred light years away, and not the star of the romulan home system. In either case, this is set in a setting where faster than light data transmission exists. The romulans would either have been aware of this impending doom DECADES before it hits thier home system (since a gamma ray burst travels at light speed, and "nearby" stars are typically in the 50 to 100ly distance range) or would have been able to examine the problem directly if it was thier home star system, and turning it into a black hole with red matter is supposed to help how in that case? No, Adams does NOT get to be thrown a bone on this. The plot is flimsy as f$#k. In either case the romulan star empire would have ample time to evacuate thier planet-- you know, since they have superluminal travel, communications, and scanning technologies and all.
Since the rest of the movie flows from this faulty pretext.... Blech!
