Avoid any expectations and you may be surprised! Apparently this film got a lot of good hype, and the result was that lots of people went to see it with high, or misguided, expectations and then immediately went online and accused it of being the most boring movie ever made.
I loathe people that say things like that! For starters, unless they've seen every movie ever made, their opinion is entirely specious and irrelevant. Second, they only think that because:-
A) They are morons who are unable to enjoy a film unless it includes chaotic action sequences, fast-cutting, explosions, and sex.
B) They went into it with expectations that were either too high, or primed for an entirely different type of film.
C) Both of the above!
This film is extraordinarily well made. By a crew of three people + two actors. On a budget of virtually nothing. Using off-the-shelf equipment and software that you may well have on your own PC. (I do!) Yet it looks and feels like a proper, full-scale movie.
The fact that it was shot entirely on location in Belize, Costa Rica, Guatemala, Mexico, and Texas adds considerably to the production values, and the visual effects (most of which you won't even know are there) again increase production values, and help sell the premise of the film.
Yes, the story is simple - but not pointless, and not too thin. The film moves at a good pace, with a clear narrative and satisfying conclusion. There is no real action, but this is not meant to be an action movie. You don't see many monsters, but you feel their presence and hear them throughout. When you do get to see the monsters, they are pretty good. Not the greatest, but certainly not bad. Nowhere near as bad as the monsters in a lot of much higher-budget, more "professional" Hollywood films. They don't disappoint, and they are actually quite beautiful, in my opinion!
Despite an arguably misleading title, this is essentially a road movie/romance, with sci-fi underpinnings. It's an adventure in exotic jungle locations. If you enjoy a good jungle adventure, then you'll probably like this movie.
The performances from the two leads are totally natural and easy to watch. The dialogue is natural too. (It was mostly improvised, but didn't feel like an improvised film. Before I watched the "making of" I just assumed that it was fantastically well-written!) There is nothing self-conscious about any aspect of this film, unlike most "improvised" movies.
Finally, and I can't stress this strongly enough - watch the film with an open mind. Then watch ALL of the documentary material on the DVD. The Making Of documentary has a longer running time than the film itself, but it is well worth it. And after seeing how the film got made, you will appreciate it so much more. As a movie, it stands up very well on its own, but viewed alongside the documentary material it is a master class in guerrilla filmmaking.
I challenge any TRUE movie buff not to come away from the experience with respect and admiration for this small team of talented young artists, who achieved so much with so little.
