Of course, while they may be in different timelines, that's two major planets the new film has blown up for the sake of angst in a character. I personally find this very lazy and rather horrific; destruction should mean something, it should be treated with dignity but here I felt it was used for quick shocks or the tired "my home and family are gone, so now I must smash and brood and destroy" characterization. I think of the planets that have been destroyed in the novels: Oghen, the many worlds the Borg destroyed in "Destiny", Palgranex. All these were treated with the dignity they deserved. This isn't simply a strength of the genre; on-screen destruction can have the same effect if done correctly. If anyone has watched "Babylon Five", the haunting scene of the bombardment of Narn comes instantly to mind. For that matter, the fall of Cardassia Prime in Deep Space Nine was handled properly. Garak's speech about the rich and noble Cardassian culture, and how so much has been lost, is very moving. I don't feel the film delivered something like this, not for Vulcan and certainly not for Romulus (Spock did refer to its destruction as "unthinkable", so that's a small step in the right direction, I suppose).
Considering that Spock spent most of the rest of the film in a state of emotional shock and recovery from the trauma of Vulcan being destroyed, I'm really not sure where you're getting the idea that there was inadequate follow-up to the destruction of Vulcan, nor do I see the distinction between how B5 and DS9 handled that scenario and how ST09 did.
Fair enough on Romulus, since Nero was the only one who really seemed traumatized by it - but, there again, keep in mind that from the POV of the other characters, it's not only a
foreign, enemy world, but a foreign, enemy world in an alternate universe's far future.
Also, I don't know if this has been discussed yet, but why didn't Nero go to Romulus in this new timeline?
A deleted scene established that the damaged
Narada was captured by the Klingons and its crew imprisoned for most of the intervening 25 years. Nero and Company then escaped from Rura Penthe and re-captured and repaired the
Narada in time to intercept Spock Prime.
