I've seen a lot of criticism for the first episode, but I actually really enjoyed it. Maybe my expectations were set too low by STD? This is way better than STD at any rate.
A lot of people have a problem with Starfleet and the Federation behaving selfishly regarding the Romulan supernova, but I'm okay with it. Nothing lasts forever, including the idealism of a galactic superpower. They had just taken a serious pummelling by the Borg, and then the Dominion in very quick succession. Of course they'd turn inwards, become less trusting, and less willing to extend a helping hand to an old enemy. I've always wanted to see a Star Trek set in the distant future, where the Federation is an old corrupt empire in decline. Separatist factions popping up all over the place, with worlds trying to fight for their independence. This isn't that, but it's a step in that general direction.
As for the Irish Romulan, it was kinda jarring, but I'm still okay with it.
