But what is Star Trek?
Star Trek is a science fiction series set during the third and now fourth millenia. It is anti-capitalist, with the Ferengi being a primary antagonist in early Next-Gen.
Star Trek almost exclusively from a Human and Federation (and mostly just Starfleet) perspective, the first Alien captain on a show is Saru from Star Trek Discovery. That's not necessarily a problem, but it is worth noting.
My favourite Star Trek show is tied between Deep Space Nine and The Next Generation (TNG). Both shows have compelling characters, good station/ship design and many GREAT episodes!! I do really like that DS9 switched to the grey and black uniforms as they are my favourite ones in the entire franchise, followed by the Wrath of Khan Uniforms and the Enterprise Uniforms from Star Trek Enterprise.
Kira and Dax really should've dated! Garak and Bashir really should've dated! Picard and Riker! Trip and Reed? Why not! Hahahaha!
