There is a certain point of diminishing return between hotness and personality. The character was handled much better this season, as was almost everything else about the show, but Felicity was just awful in season 4 and most of season 3.
I agree on the character part, but I'm with Squiggy, she's a hottie, so much so that I can forget the other negatives. She was better this season, so that doesn't hurt either.
The final episode was great. I kinda felt bummed Poseidon offed himself cuz he was an awesome villain for Arrow. Curious to see who stays and who gets killed off. AOS and Arrow are my 2 favorite comics based shows right now.
