Unfortunately Golan-Globus ruined the Death Wish franchise, which really should have ended after Death Wish.
The first movie was awesome. My favorite part has to be when Bronson encounters the muggers on the subway. The scene is so raw and minimal that it is also scary, especially when his character shoots the muggers several times, even when they are clearly incapacitated.
The subsequent films really ruined it, turning his character into a generic action hero who uses more ridiculous weapons against the more typical sinister "bad guys."
