...if you ignore the (very outer fringe) "science". Reviews are very mixed here, I'll give it a middling one.
I didn't love, nor hate it. It's an alright film for a midweek night. It's certainly no "indie gem", but on the small(ish) screen it works well and it does stand out IF you think of it as (yet another) found footage film and is a mildly refreshing addition to found footage sci-fi.
There's a British "quaintness" to it, but the acting lets it down at points - and that's across the cast of which there are few.
For me, the biggest let down was the soundtrack - the reimagings of a parallel universe Nazi-Bowie (yeah, we get it) were clumsy and musically bad, seemingly with lyrics written by someone that heard an Editors album once but it was "too edgy" for them and the world doesn't need a pastiche of a 3rd rate Joy Division tribute act - unless that was an actual joke. Just because you have a friend that'll do your soundtrack cheap... which is odd because the use of The Kinks worked I felt and must have cost some money.
There's a moment towards the end of the film where one of the female leads has "written her own song" and that's the point I checked out mentally and my suspension of disbelief really faltered, just horrible drama-school dross.
The director might be one to keep an eye on if they stop roping in friends and hire professionals and do some reading up about science, but almost an enjoyable film.
