Yes the genre is getting saturated with low-budget found footage movies, this is surprisingly decently executed. The plot is also nothing new but the arc over the 3 films is quite decent.
The acting at first appears quite poor, until the creepiness really kicks in, which helps the scares surprisingly.
The set is pretty cool and confusing so where corridors lead etc stays surprising despite not being a massive set.
A lot of the scares are what we'd be worrying about in that situation, the turn of a head, the shadow behind you.
The series are worth a binge watch if don't want to think too hard or take it too seriously.
