Mark Wahlberg gives a good performance but the movie is kind of sloppily put together. The story line is weak. All actors apart from Mark play their parts poorly. Much of the movie is quite not-believable.
I did like the (tiny) parts of the movie that had to do with judging distance, wind speed and projectile mechanics but the rest of the movie is too amateur. On the back of the DVD it says "Along the lines of the Bourne Supremacy" or something to that effect but this movie is like a poor cousin. Much like what the 'Go-Bots' were to the 'Transformers' - if you know what I mean. Avoid unless you're getting this for free.
