It had that waiting to start feeling well over halfway into the thing, so there's that to start with. I call it a thing because I think thing is probably what it is. It's not a story, if you try to view it as such you'll just come up short and see it as a modern hack of Fear and Loathing on a beach. Mathew would not have been my first choice for the gig, he's lacking the sardonic nature that Moon Dog is clearly supposed to possess. However it's still Mat and he doesn't suck.
Having called it a thing, when it's all said and done I liked the thing. I liked it because it was entertaining and it was at least somewhat different. You have to ignore important plot development lines that either never occurred or were never divulged to the audience in order to like it.
If you can't do that then don't bother with it. However if you can then I recommend this as an adult viewing at home on a dark couch with either a doob or a cocktail to accompany you.
