It’s just not that good…
Bad things: horrible music, it just didn’t fit most of the scenes. Either too much orchestra or just way too dramatic for a simple scene (him simply walking in a forest doing nothing). Also the tone of the music didn’t fit the gloomy atmosphere, it would better fit gladiator or some war movie.
Quite predictable, but don’t want to ruin why.
No real chemistry between Del Toro and Blunt, which made their “love” seem really forced and tiresome.
The action was too focused on being gory rather than exciting or suspenseful.
The writing isn’t very good either, lots of cliches “prodigal son returns” - “dog eat dogworld” etc…
Good things: transformation scenes were impressive, schizo-twitching and bones cracking apart were nicely done.
From the trailer I was hoping 7.5 but it really is a 6/10
