The movie can be quite graphic, but the suicides on television are not over the top and not very realistic. It is disturbing however, and definitely not bloodless.
A woman kills herself by electrocuting herself by putting a toaster in her bath, we see the whole process, but there's no gore.
A man commits suicide by stabbing himself in the stomach. This is probably the goriest scene.
A woman commits suicide by putting a gun into her mouth and firing, we only see the impact very briefly. There is some splatter but the camera quickly cuts away.
A man commits suicide by putting 2 guns onto his head and firing. Blood splatters.
