This is just a loose mish-mash of two distinct stories in the Hellblazer universe and they managed to even mess that up. The tactics John uses here make no sense, and are just a deus ex machina the writers pulled out their ass because they didn't have enough imagination to come up with something that works. Of course they could have just used the original plot... which worked way better.
Read the comics.
Way.
Way.
Better.
The only right thing in this sorry excuse of a story is the voicing.
