It can be pretty divisive, but I enjoyed it. In a few ways, it diverges pretty significantly from the traditional Trek look and feel, and has to explain away a fair number of inconsistencies, but it has its own unique identity and a pretty solid cast. The main character is probably the source of most of the division, and I found myself liking her a lot in some cases and getting incredibly annoyed by her in others. It’s a very emotionally-charged show, which works for some people (I tend to like having my emotions played with) and it’s visually gorgeous.
So I’d say it’s definitely worth a watch, but with medium expectations. One of the nice things about how the plot is structured, is that there are a lot of twists and complete “fork in the road” type devices, so if you’re tired of a storyline, just give it a few episodes and everything will change (at least for the first couple seasons). I’d say go for it.
