Pros:
1. Both Will Smith (John Hancock) and Charlize Theron (Mary) give great performances.
2. The emotional scenes, with thanks to the acting and well-timed pauses, land with great effect.
3. The humour is fantastically dry and dark, which prevents the film from becoming stale.
4. The action scenes are well-choreographed and entertaining.
5. The CGI and special effects, aside from a couple instances, look great and still hold up 12 years later.
Cons: 1. There are a plethora of really strange editing and camera angles which take you out of the viewing experience. 2. There are a couple plot-holes. For example, why did Red (Eddie Marsan) only take Man Mountain (David Mattey) and Matrix (Maetrix Fitten) to confront Hancock at the hospital, after it had already been established that most of the prison population was there because of Hancock? 3. During the action scenes, obnoxious and corny stock action music is played. 4. The movie doesn't focus enough on the philosophical reasoning behind a superhero negating their duties, and whether or not they should have free will to decide their superhero role. 5. The entire sequence featuring Hancock and Mary fighting in LA not only has the worst looking special effects, but the conflict just feels really forced.
