If you want to watch this movie, DON'T READ ANY OF THE DESCRIPTIONS OTHER THAN THIS ONE AND DON'T WATCH THE TRAILER. I was very happy I did not watch the trailer or read any descriptions prior to watching it. They give away WAY too much information.
The story itself is cheesy and lacks development but the focus is the relationship between Denzel Washington and Mark Wahlberg. Their chemistry is really good. Wahlberg tries too hard at some points but overall it's fun to see them together. They make you want more of them and less of the actual story.
Paula Patton's performance is off. Her facial movements are unnatural and too exaggerated. Her chemistry with Denzel is painful. Being the only significant female in the movie, it's disappointing she doesn't have a better presence; but her character and story line lacks a lot so it's not that big of a deal that she doesn't do a good job.
By far the biggest complaint is the terrible lighting. It's entirely too dark at times.
2 Guns could have been more of a quirky and memorable movie had it been directed by the Coen brothers. It doesn't win any awards for quality or depth, but it's a decently entertaining movie. Worth a watch if you're in the mood for a slightly dark action comedy.
I usually put a video of the trailer here...BUT...read above!
