Saddam's Secret Tunnels is a roughly 45-minute History Channel special about Saddam Hussein's tunnel network under Baghdad. The TV episode appears to have been made during the period in 2003 after Uday and Qusay Hussein were killed but before Saddam Hussein was captured. Due to the timing, the information is very limited, outdated, and highly speculative.
Most of the special is just "experts" offering theories about Saddam's tunnels, computer animations of the imagined tunnel network, and video footage of people with flashlights walking around in unremarkable bomb shelters under houses and government buildings in Iraq.
There is very little to see in this TV special now, and it was probably not even worth watching when it aired. Someone trying to learn more about the history of Iraq and the Iraq War would not find this show useful.
