I'm sure The Spectre fans were quite happy with this episode. It was a nice nod when Zed had a vision of green mist around Corrigan.
As for this particular Constantine fan... I liked the previous one better, but can't say that this was a bad episode. It was nice to see Midnite's sister make an appearance by the way.
And is it just me or are they letting Constantine smoke more and more prominently as of late? Not just that he had a *** (no need to censure this Hype, I'm referring to cigarettes not a gay person!

) in many scenes, but I'm also sure I've seen him exhale the smoke.
