I really like the movie for its acting and unpredictable story. Very strong and believable performances. The storyline is very simple, but disturbing. Mark Patton gives us a hilarious over the top character. I think the real horror is in the uncertainty and not knowing what is going to happen once the drugs are swallowed... There was definitely more room for a background story of the main characters to get more attached to them. But Colon (no pun intended) and Koch feel very believable in their stressful situations. Some funny and uncomfortable scenes aside the movie gets its tension across be it not in slasher/gore/bloodbath style. So not your average Saturday night movie, but worth the watch.
