Started off so well, why ruin it

Rating: 6/10 (29 November 2019)

The first half of the film is really, very effective. Superbly crafted, from the refreshing idea, to the filming, to the music. Goddam that tall man scene is one of the most frightening things I've ever seen in a film. I am giving this a 6/10 for those reasons.
What worked so well is that it was very psychological, until a certain point -- the monster is only visible to the infected person, and thus to everyone else, it is like it's in their head. The infected person is totally trapped.
... and then they ruin that on the beach scene, which for me watered down all the remaining scare factor to pretty much zero. They made the monster 'physical'. It's there and capable of doing anything a regular person can except it's got a magic invisibility cloak on it for everyone else. This takes a psychological fear into a 'scary killer monster' fear. Now the protagonist is no longer alone, they can (with some level of coordination) get help. And moreover, the monster is no longer invincible, because they can physically be pushed away/delayed from getting to the main character. It's automatically less scary. Such a shame.
