I like the new UI, I think it feels Trekkie without being dated and '80s-ish like a strict LCARS UI would have been (like in Bridge Commander, for instance).
This is pretty much where I'm at. I've seen an awful lot of QQing and demanding refunds over the years (been playing and been a lifer since closed beta) and it always makes me laugh. Meanwhile, I'll enjoy the game and get out of it what I paid for it and be happy.
