Oliver uses his secret persona to right societal wrongs and transform the city to its former glory. He must also contend with outside forces attempting to take over, but he feels its time he left Starling City with the hopes of beginning a new life.
All told, I'm still pretty happy so far with Season 4. Dhark is a tremendously powerful villain, though he feels extremely impersonal compared to the best villains in both Arrow and The Flash.
"Haunted" was a great Arrow episode that eventually had to settle for "pretty good." Indeed, Matt Ryan and Stephen Amell's chemistry is a big part of what makes this installment sing.
Not even John Constantine could conjure up enough spells to make "Haunted" completely fix all the issues with Season 4 of Arrow. Thankfully, the magic man's appearance did bring some much needed excitement to the lumbering main story line.
"Haunted" was a terrible mess. I'll admit to my own under-appreciation of NBC's Constantine, as well as the implicit enjoyment behind two DC heroes of different networks crossing over, if only such rushed setup hadn't cheapened that thrill.
Constantine is a refreshing character with a unique personality and set of powers that I'd love to see more of in the DCTV universe in a similar way that Hulk is to the Marvel film universe.
"Haunted," the much-ballyhooed Constantine episode, is a success simply because the writers find it so easy to integrate the character into the plot, which is about as easy as flipping a switch.
NBC's canceled Constantine series lent The CW drama its main character for a totally awesome crossover that honestly seemed too good to be true. But it happened, it was real, and it kicked some serious ass.
