Constantine
Now, this is rather untypical for me. “Constantine” is a superhero horror film. I am NOT into horror movies AT ALL. Still, I watched Constantine.
Especially because it features Keanu Reeves as the main actor. A must-watch(-actor), in my opinion.
Plot
John Constantine, an occult detective, is called to exorcise a possessed girl. He exorcises demons back to Hell to earn favor with Heaven, which he seeks salvation from because of an suicide attempt in his youth.
He helps someone learn the truth about her sister's death while unraveling a much larger and darker plot.
That's about as much as I can give away without revealing as much as the wikipedia article on the movie does.
Reception
On rottentomatoes, the movie averages at 5.4/10. I would tend towards 7/10 though, even though I am not favourable of horror movies at all.
Still, the tension (and hey, Keanu Reeves!!!) was great and I liked the movie a lot, despite some rather gory scenes.
