Horrible watch, won't watch again, and can't recommend.
This is what I like to call a bar bet movie: someone bets someone else that they can make a movie about a ridiculous concept and then actually tries to win the bet.
Not that I'm a big fan of poop humor or drug humor in general, but this movie is kind of hard to watch at points.
Ignoring that I would probably be easy enough to get "gifts" for the aliens, the weird sociological terror they get into to not get the "gifts" is absurd, which looks to be the intended humor, but it doesn't land for me, at all, for the entire movie.
Quite possible I'm just not the target audience for this.
