With all the great reviews I suspected a hidden jewel, and it kinda was. However it annoyed me a lot.

Especially the dialog was extremely hectic and kind of retarded in the first 30 minutes. It got a bit better after that, but never really good. The actions and decisions were of people that just did not think, something that doesn't fit in a movie with a smart setting like multiverses. imho it only fits with comedy and some exceptions here and there, but that's just me.

One of the flaws that showed itself a couple of times was the time flow. Time is not really consequent throughout the whole movie. In 1 scene someone drinks up a bottle of wine within a minute, and on a few occasions people were gone for a longer period of time (10-20min) while in the house itself no more than 5 minutes were passed at best. This could be explained by the major plot twist in the end, but it would be nice if there were made 1 or 2 remarks about it if that was the case.

The movie is also not giving the viewer time to make their own construction of the situation but making a few emotional scenes right after an info-dump and repeating this process.
And when the characters finally start to understand how complex the situation could be, they decide to pop open the alcohol and get wasted.... seriously?
It brings the movie to a dramatic impasse that is completely unnecessarily and just slows down the mystery.

Luckily the movie manages to get some points in after that. More focusing on story development, having some very interesting plot twists and using the mystery to its benefit in stead of for the drama.
Those last 15 minutes are a good home run, and the movie sets up a completely other pace and setting. Suddenly moving from a group of people with no clue what's going on, to one main character with an objective.
Maybe they should've done this from the beginning to make it more interesting. The girl (Emily?) who took on this role was from the beginning one of the few actors I did not have many complains about, and was doing a good job.

Usually I am a big fan of the 'quantum multiverse' theory worked into a movie, and the concept in this one is very nicely done. But even though they tried (and to be fair the creators have a good grasp on the subject) it kinda failed with the overly dramatic setting and insulting the viewer by letting characters make dumb decisions.

Since it is a low budget movie, I decided not to be too harsh on the rating itself (it really is a movie that can match itself with the high budget ones) and I definitely would upvote for a remake with some better scriptwriting for dialog and some actions. Because I think that this flick could be even better.
