J. J. Abrams should have skipped the time travel and kept most of the core story and implant some other threat, instead of time traveling drillers from Romulus.

Also i for one do not accept the old Spock from the movie, as the true timeline Spock and instead prefer to think of him as some other timeline’s spock because the real one would have done more to save Vulcan.

Point 3. The interference generator for beaming was not on, presumably, there was no threat detected by the enemy ship (Enterprise was hiding in the clouds and as pointed out in Point 6, there was no other space defence. Most of neighboring ship got wiped out when they warped to Valcan with their shields down and got destroyed anyway.) Another possibility was that the generator was destroyed in when Kirk sky dived down to the drill at Valcan. The generator was placed at the drill. The enemy ship may not have the parts to replace the generator. And apparently, the enemy ship had no shields, and I presumed that the enemy ship relied heavily on active weaponery and the generator to prevent boarding attempts. They didn’t beam more than 2 people into the ship as it was supposed to be a stealth mission with primary objectives to rescue the captain and stop Nero.

Very enjoyable.  Fine.

However, the things that annoyed me were not the time travel issues.  They were basic tactical issues.  OK — and one bio issue.

1.  Bio issue.  I don’t buy the extra-big creature on the damn ice field.  I don’t think the energy balance is going to work.

2.  Tactics.  A really bad-ass spaceship is heading to Earth after having clobbered Vulcan and Spock is going to have the Enterprise go wandering off in a different direction?  Um, no.

3.  Tactics.  If you can beam 2 guys onto the enemy ship (and how did they manage that?) why don’t you keep beaming more fighters in until you are stopped?  And start with more than 2.

4.  Security.  Your Joe Random Starship Captain is going to have the sooper-sekrit defense codes?  I do not think so.

5.  Chain of command.  Captain, acting captains, and whoever else has the helm running off of the bridge.   Don’t people get court-martialed for stuff like that?

6.  Space defenses.  Hey — what a concept.  Earth and Vulcan sure could use them.

Until someone actually travels in time this is all speculative. Star Trek takes many liberties in many areas of science. For them to have their own rules for time travel is less of a problem than many of the other scientific errors. It is valid to discuss time travel in ST based upon ST’s rules for time travel even if many physicists have a different view.

Abrams intentionally set this up so that he can do whatever he wants in future movies. This freedom is helpful to Abrams in making movies, and perhaps we have to accept this as the cost of getting new movies. It is bad for ST in the long run, assuming that there will be more Star Trek in the future beyond Abrams’ movies.

I wouldn’t mind having two versions of the Kirk Enterprise (original and Abrams) if he had limited his changes to that era. I wish he hadn’t made such a drastic change which affects not only new versions of TOS but all versions of ST.
