Interesting...
I like other pieces of the director's work, it's got a good cast and the trailer that I watched recently looked good.
Always fun to have similar films come out around the same time (this and hopefully Cold Skin) for interest rather than negative comparison. Also that they're both from Spanish origins! I'm sure they'll both be movies worth watching.
Liking the art/poster work for both films too - blue hues naturally!
Let the love of the fishy-frog people commence; fun for all! (Cold Skin has human man with fishy-frog lady and this has human woman with fishy-frog man; no offence to non-heterosexuals!)
