I abandoned Sleepy Hollow too. Based on a preview, I'm hoping that Dracula lightens up after he gets his daylight cure... so far the environment has been 100% dark and dreary.
I suppose that is why the womens costumes are so bright? Yeah, it has been quite bleak and dreary.
How is Arrow? I've avoided most of the superhero shows on networks like the CW as I've found them to be lacking in the past.
I've felt like you about CW's past superhero shows - given that, I am not sure you'd be too happy with this show.
There are things I like about Arrow and a lot of things I don't.
Don't like: I loathe the CW forced soap opera business and shoe-horning so much of the DC universe into the show.
Like: it not bad as far Oliver Queen (Arrow) himself when he is Green Arrow. I like this Ollie a bit better than the Smallville one.
I'd say try a couple of episodes, but do not expect much.
