This was a really interesting take on the genre. I love that about 48 hours where teams try to subvert the expectations and end up with something crazy and original. This was exactly one of those situations. The story itself was a bit thin in places but it held together well enough that the concept was able to shine through and keep the audience engaged nicely.
Years ago it seemed like every other team went with the mockumentary route and it just wore on you, but now that they're not the hot ticket anymore it allows films like this to shine without the baggage.
