Leaving the original aside - pretty enjoyable

Rating: 8/10 (16 October 2017)

Okay, I haven't seen the comics/graphic novels this is based on. I've seen the TV show with Matt Ryan and I've heard that it comes much close to presenting the true original Constantine than Keanu Reeves does.
That being said, when I got around to finally seeing this I was pleasantly surprised. Reeves does a competent job, but I think the movie is very much buoyed by Rachel Weisz playing the unwillingly psychic detective and her unfortunate sister and by other characters in the ensemble, notably Tilda Swinton playing a very "complex" and other- worldly Gabriel and Peter Stormare doing a bang-up job as Lucifer himself.
The movie has a lot of special effects and in my opinion they are all pretty good, and the action is varied enough and persistent enough that you neither get bored waiting for it nor get bored in the midst of it.
In the course of suspending your disbelief you have to accept that God is pretty much a stickler for rules (about suicides, e.g.) and yet is enough into dualism that he is willing to give the devil's side a sporting chance at winning the game if he plays his hand right. But this is far from the only movie with such conventions. I don't claim that this movie has tons of subtle character development or deep theological truths, but I found it enjoyable. More enjoyable than a lot I've seen.
