I'm so on the fence about this season so far. Many of my favorite moments of the series have been in this season:
- "You lie to the Russian stink eye and bad things will happen to your junk!"
- Everything with Lauren & the Morrigan.
- Bo having sex with Flora/Lauren while in Dyson's body.
- Tamsin's dance off in "Let the Dark Times Roll."
- Lauren being an absolute badass when the Dark Fae captured her & Crystal in "Turn to Stone."
- Nearly everything about "In Memorium" (except for George Takei's performance).
But there have also been a bunch of problems this year:
I've felt like a lot of the individual episodes haven't held up very well plot-wise; even by Lost Girl's standards, which often weren't that high to begin with. The larger story-arc with the Wanderer has been largely lacking in major developments in the first half of the season, totally squandering the awesome cliffhanger development from the end of Season 3. And even the stand-alones don't feel as significant as they used to. It feels more like every is just kinda wandering around while random stuff happens. I preferred the more structured approach in the earlier seasons revolving around Bo & Kenzi's paranormal P.I. firm or Bo helping Dyson with some Fae cop case he was working on. We haven't gotten much of either this year.
A lot of the rules about Light & Dark seem to have been totally ignored. Bo & Dyson totally got busted for crossing party lines during their recent hook up. That fits with a lot of what was established way back in Season 1. But after the end of "La Fae Epoque," everyone just seems to forget about it. And then, in "Groundhog Fae," some prominent Light Fae like Dyson, Trick, & Hale are having a Yule party at Bo's house, which would presumably be Dark Fae territory now. Or are we supposed to assume that Yule is a holiday like La Shoshain where the normal rules of Dark & Light don't apply? (But then, why is Tamsin forbidden from entering Bo's house while the Light Fae are in there?)
Also, why has the Morrigan suddenly lost all interest in exterminating claimed humans? I suppose that could have been just a baldfaced ploy to embarass Hale but that hasn't been made very clear. Nor would it make much sense why the Morrigan would have such a vested interest in removing Hale from his position as Ash. (With his somewhat naive lets-all-get-along agenda, he would have been much easier for the Morrigan to exploit & manipulate than Lachlan or Trick or just about any other potential Ash you might think of.)
I also feel like the romantic storylines have hit a dead end. Kenzi & Hale got together about a year & a half too late for me to care any more. (And it doesn't help that we keep getting episodes like "In Memorium" & "La Fae Epoque" that totally highlight the much juicier prospects of Kenzi/Dyson.) Dyson & Bo are now kinda back together with hardly any fanfare, which doesn't feel right. Bo & Lauren aren't together right now but the show can't really come up with any convincing reasons why they aren't. Bo/Tamsin is hardly going anywhere. And, as Vex so wisely pointed out, Dyson & Lauren don't hate each other anymore, so we don't even have that conflict.
