To borrow the words of the previous reviewer, that went from gritty to gash very fast.
This show had the guts to kill main characters and the skill to keep you on the edge of your seat, but throws that away with an anaemic ending. I was expecting the gut punch of a shocking death, of a twist, of a conclusion from left field that I didn't expect and that would be fitting of the episodes that came before. Unfortunately it seems that the writers couldn't muster that.
Bodyguard is still a quality series, it's just a shame that they couldn't stick to their guns for the conclusion. I was also waiting for a car bomb to take my breath away, what I got was the credits rolling and a distinct feeling that there could have been more.
