I have never wrote a review on any of the shows though, but i've been closely following most of your reviews on Arrow.
As i have seen the show is getting more and more exiting as it progresses through the season, not yet half way but it feels like were already aproaching the finale. The excitement is building. Can't wait for the the second half of the show to see what we have in store after winter break.
Speaking of "Haunted" the episode has been quite better like expected, following the hint of Constantine appearance, both in flashback and in current time as I had guessed. I haven't watched Constantine but his cameo on this episode just spiced up everything as his performance was great especially his dialogue.
Once again we see the Darhk-Lance un-easy alliance and how is going to benefit the team arrow. But as some light shed on the death of Diggle's brother, i do or don't think that Diggle will be much driven to get some payback as he has always been.
The White Canary being officially brought back was the peak of the episode, though i thought that it was too soon and the monster from the pit was too brief too.
