In all I didn't think it was too bad. However, I don't really see it as a Star Trek series. It sure didn't feel like one, and it has removed some of the core themes that Roddenberry insisted on (i.e. little to no conflict between senior staff, etc). The Klingons didn't feel right, and they could have dropped them speaking in Klingon with captions fairly quickly. The cursing and the gore are obviously huge departures too.
In all, I feel they are a little thin on the ground with core characters. I don't really feel much for them main crew (though Jason Isaacs is a fine actor - I just don't know what Lorca stands for except being a hard-arse as yet). In all, I chose chose to think of it as an adult, action sci-fi series as it wore on, and that worked for me.
I would still love to see another Trek series continuing the timeline we all know, though...
