I've been watching one episode a day of S3 and finished it yesterday. While I think this season teetered on Flying Off the Rails (the whole film studio/Phantom plot, while fantastic to look at, belonged in a different show, I think, but the identity of the Phantom was a totally unexpected surprise of a callback), I still looked forward to my daily episode, just for the production design alone. (I did miss Moka Efti, though.) And Graf singing to his lover at his birthday party while his boss accompanied him on the accordion and Charlotte and Gereon necked in the hall dinged my hard little heart (see also: Greta).
I kinda wish the season hadn't been a flashback from the market crash as it took away some of the power of the last scenes (which from our history books we knew was going to happen anyway). At least evil Wendt got screwed a bit. I still don't know what Helga sees in Nyssen (or why the Coincidence Fairy kept having Charlotte see Helga around Berlin, he said vaguely so as not to spoil much). Toni! What is *wrong* with you?
I assume/hope/pray there's going to be a fourth season, otherwise they wouldn't have (sorta) introduced Charlotte's unknown brother, a handsome athlete. Also, where is that traaaaaaaaiin!?!? More, bitte!
