Well. I was enjoying this season so very much and then . . . kablooey.
As someone who'd been okay with the Logan/Veronica relationship--especially since the movie and this season made it clear that he'd really been working on himself--I was perfectly fine with them NOT getting hitched, but also interested to see if they could sustain a marriage. The Navy was the perfect excuse to have Logan away 80% of the time and we could have seen Veronica struggling with that or not, whatever. She'd still be on cases and I don't think marriage would have dulled her cynical edge overmuch. Blowing Logan up was pure selfishness on RT's part and shoots the whole franchise in the foot. Which I think he kinda wanted? But his "vision" for VM's future isn't sound.
RT goes on and on about "noir," but taking VM out of Neptune undercuts one of the genre's great conventions: the city (or town, in the case of Western noir) as a character and the detective's cohorts and nemeses woven into the fabric of that setting. The lawyers, the stoolies, the obstructive cops, the crappy P.I.s, the corrupt politicians, the tough guys; VM did such a fantastic job of establishing characters to represent all of these. WHY does RT think having Veronica start over with a clean slate in new place after new place would be the least bit appealing? Noir P.I.s may be loners, but they have networks they carefully cultivate and rely on to do their jobs. Itinerant Veronica will never develop a network anywhere, and I couldn't give fewer fucks about getting to know new people every week when I was happy as hell with the ones we already had and trusted RT to add compelling new characters as necessary. I've loved Veronica from minute one, but not even the strongest, most well-drawn hero/antihero can live in a vacuum. And that's what RT's new concept for the show would be asking her to do.
When I think "on the road," shows like Route 66*, The Fugitive, Kung Fu, and (bleargh) Highway to Heaven spring to mind. The only great (for a while) on-the-road show I can think of is The X Files, which worked because of the chemistry of the leads and the fact that the setup allowed for overarching storylines and recurring characters. And then there's the cliche the majority of on-the-roads have in common: "Stranger arrives in town, touches lives, and leaves . . ." which, no fucking thanks.
ITA with the idea of keeping Veronica in Neptune to explore the ravages of gentrification. That could have been great. Instead, we get Logan gratuitously murdered to further an agenda that will wreck the best of what RT built. He seems to have pinned all his creative frustrations on the presence of one character, so he killed that guy in the service of a fucktarded creative plan. Talk about cutting off your nose to spite your face.
*Apologies for not italicizing titles--that function's not working for me for some reason.
ETA: Star Trek and other space shows in that tradition are also "on the roads" (to me), but they work because your city/network of characters is portable!
