As somebody who is just climbing aboard, can I offer 'the jury is out'?
On the plus side the series appears to have carried the old Star Trek flag far better than more recent ST creations. Simple stories, entertainingly presented, if a little too reliant on magic details. If we are absolutely honest, the scenery wobbles nearly as badly too! Ah the nostalga!
There are some pretty poor episodes too (last weeks?), and Sorbo is less of an actor than Shatner ever managed.
It will be interesting to see how my opinion changes as the series progresses
