The rest of it? What a mess. I don't even know where to start. The Trek Tropes go deep with this one. Main character sacrifices himself for the greater good...yet is also not really dead. Supporting characters' genuine grief over said death cheapened by the Deus Ex Machina resurrection of said character. Episode/movie/season ends with a quip from the captain. Ham-fisted lesson about humanity and togetherness. Fan service cameos. Predictable villain death that tries hard to be satisfying. Innocent looking first contact race that dresses in flimsy fabrics and "there's more to them than meets the eye." I mean, I half expected one of the synths to be named Weena after the character in George Pal's "The Time Machine."
And on the subject of villains, they really dropped the ball on this one. Was the main villain the hunky Romulan boyfriend? The Romulan/Vulcan Star Fleet mastermind? The Romulan boyfriend's hot yet evil sister who was frankly a bit over the top yet arguably the most interesting? The evil sister of the sister of the synthetic that kicked off the whole show? Jeez, guys...pick a single baddie and make them the focus.
Finally, I'm getting really annoyed with the thing where the space battles are premised on the idea that "more is better." In that last standoff, there was what...218 Romulan ships? 218 Federation ships? And they're all a few hundred yards from each other. I get it...it looks cool on screen, but tactically speaking a whole bunch of capital ships bunched up together is a terrible idea. From a dramatic perspective, the most exciting space battles in Trek are one ship against one ship (Wrath of Khan, anyone?) or a couple ships against one stealth ship (Undiscovered Country).
Oh, and finally finally...the gigantic missed opportunity with Jeri Ryan and the Borg cube. You've got Ryan - who despite her being "the one they hired to sex up Voyager" is a really good actress - a cube filled with ex-Borg smack dab in the middle of a story about synthetic vs humans, and if you really wanted an epic space standoff you've got a Borg cube...which even operating on a limited capacity could have seriously fucked up the Romulans before going down. Hugh crashing it into the Romulan flagship and what not.
So much missed potential in this series.
