I just finished watching it and I gave it a D+
Biggest reason I didn't care for it was it is barely recognizable (IMO) to Star Trek, every time I saw something new and "improved" I just cringed.
From the military dress uniforms with hats no less..really?
To the communicators and even the new boots, ughh what were they?
I guess my big thing is I never liked the Abrams style Trek, he always seems to try to copy and then one up everything that already happened in the previous series.
The other thing I don't like is the over the top-ness, don't get me wrong, I love a good action movie but you can't throw a huge budget at something and expect it to be good.
I could go on and on but TBH I don't feel like typing that much.
