From a great start to a disappointing ending

Rating: 4/10 (31 October 2015)

I watched this movie with my best friend last night, and we were left wandering why the 2nd and 3rd act were so bad. A great beginning, it was creepy and we were exited and scared, BUT it became boring soon after, i knew nothing was going to happen and that she was just going to run from 'it', and eventually it led to an anticlimactic finale, it was left on us to decide whether 'it' was gone or just few moments away from killing them. The original idea of the film was OK, a STD king of monster never leaving you at peace, with it's possibility of killing you eventually very high. But it wasn't executed well. The rules changed throughout, from 'its' appearance to 'its' killing methods... And the jump scares were obvious, we laughed instead of actually being scared. When the film ended we were bored to death, it sucked the life force out of us and we weren't scared at all. I gave it a 4 because of a good start and nice scenery, everything else disappointed. P.S: 'scary' music was terrible.
