actually, there is an explanation, but not in the movies. it's in the tie-in comic books.

romulans is exactly the same in this movie as in the rest of the star trek world. romulans stemmed from the same biological background as the vulcans, but they moved to a different planet a couple of thousand years ago and have evolved independently ever since. during that time, the vulcans developed the logic religion, while romulans keep to their ancestor's more violent and free-for-all ways.

actually, we dont see other romulans in this movie other than those on the narada (nero's ship).

the reason why nero looks very different is bcoz after their home planet destroyed in the future, nero and his crew went on a rampage. they killed the romulans high council bcoz they failed to stop the planet from being destroyed. they wiped out a fleet of klingon ships who're defending their turf. then they wanted to kill spock bcoz he also failed to save the planet. in doing so, nero became a rogue entity. they shaved their heads to purge themselves, and tattooed themselves to remind them of their lost. also, nero has a bite mark on his face, which he got on a klingon prison planet. this will be in the deleted scenes.

Wow thanks for that. Why didn't they include that into the movie? Most people would be blur or think it's a plot hole.

I enjoyed the movie as an action movie that happens to be set in space (or the Trek universe) but I'm one of those people that don't think it's quite Trek (anymore).

I certainly didn't expect to hear Beastie Boy's Sabotage in a Star Trek movie

When Spock and young Kirk met Scotty on the ice planet. Scotty talked about how he did some transporter experiment with Admiral Archer's beagle that didn't go well 

Watched it yesterday and like it. Overall I give 8/10. The main thing i dun like is Sylar as Spock ... It's just seems not right at all ...

i don't understand this part. how did scotty know that he needs to wait for future spoock and kirk on the ice planet?

huhu..this movie really best..so far the best movie (angel & lemon also) for year 2009

i dun understand with the kelvin design. in wiki its stated that according to Gene D's rule, all star trek ship must have paired warp engines... how come kelvin only has one?

wen enterprise removed the core into da blackhole it created HUGE explosion...bt how come when kelvin rammed into nadara, only small explosion... it still had the core right... should't the core explode?

if u're talking about the red matter, when kelvin rammed into the narada, the red matter is on the narada. it's safe.

but when the jellyfish (spock's ship) rammed into the narada, it was destroyed. its destruction ignited the red matter, producing the blackhole.

correction... i think the red matter was inside spocks ship all along.
when kelvin rammed narada, the red matter wasnt there.

25 years later when spock's ship came through the black hole, they captured the ship, spock and the red matter inside it. but the red matter had been inside spocks ship all along.

when young spock rammed the prime spocks ship into narada, the red matter was still inside and thus ignited when it crashed into narada.

wth is the red matter anyway. its just plain preposterous.. so much for sci-fi

read the countdown prequel comic already ..the narada looks very different in there .lol

Anybody caught the reference to admiral archer ?
