Unless very good .......

........ Only had occasional very short audio dropouts.
Picture quality is very good on Samsung UHD TV.
Whether the player to skip now on Samsung TV and the Prime-app are on the internet (Unitymedia 67.000 kb / s)
or at Amazon streaming service that's hard to say.
At least my internal network (WLAN AC and Gigabit Lan) is otherwise fast enough to handle 1080p and
Dolby Digital 5.1 inside the home to stream flawless!

The film as such is not megaschocking, but overall very well done.
From the story her something different than the usual "Teenes in the forest, or in an isolated hut" stories.
The pretty actress is convincing in her role perfectly.
Since my requirements in terms of horror are relatively high, I would recommend this film by no means a masterpiece
call, due to the unusual action but as well call worth seeing.
Only the circuit a little lame.
