Poor script, poor performances, poor photography, poor budget (includes only the former military submarine probably with no cost and most of all characters which reminds the backyard of a multi apartment building. The effort to make it a graphic scenery fade away by the characters themselves probably inspired by the memories of the author of the script.
The best part of the movie is the opening animation scenes... for about four minutes which open your appetite and expectations but the rest is boring... pity for writing this!
