Siren is a very glossy affair, very professionaly made, with good performances and an interesting attempt to bring Greek Mythology into the contemporary horror film.
This British horror is in many ways a very retro horror film, relying on good old suspense and atmosphere to drive the plot forward. However, the plot also happens to be wafer thin, and eventually, despite its best intentions, Siren becomes very pedestrian.
It has a relatively short running time and never outstays its welcome, but some much needed plot twists or revalations never materialise and the film ends up as a rather predictable affair.
A pain free experience but not one I will be repeating in the near future. 3 out of 5.
