I felt Rowena's death more than you, but I really wish it hadn't come so early in the season. I knew she probably wouldn't survive but I thought she'd go near the end, not 3 episodes in.

actually I'm BUMMED they killed of Alex's Belphagor so soon. He was the only good thing about this season so far.
AGREE. I was really enjoying him and he had such interesting potential. Why would they dispatch him so quickly and easily?? AARGH.

I can see potential fun storylines with Soul Power Rowena as the new Queen of Hell (the rate they are getting through major demons she wouldn't have much opposition even without the souls) and maybe Ketch as her side kick enforcer, but this writing team lack the imagination to follow through on such tasty possibilities.
Yeah, it's hard to imagine they're going to do anything with that, but maybe we'll at least get some good fanfic out of it. I'm already itching to write some about her as Queen of Hell, myself. And Ketch as her enforcer is a BEAUTIFUL idea which I might steal (with credit!), if you don't mind.

I'm losing hope that this writing team will be able to deliver anything decent as the boys' swan song.
Same. I thought after last season's finale that they were going to shake things up and go in interesting directions, but this season is not shaping up well so far.
