Probably not actually this, but fuck I can't think of any better answer. So this.

The first one was a good flick. It was a quotable dad-fantasy/spy movie where Albanians, the least-popular European ethnicity, get torture-murdered by an inventive Leeham Neeson until he gets his daughter back. End of movie, no sequel necessary.

The 2nd just kinda sucked, and the whole "oh but he is kidnapped and the daughter has to save him" reversal lasts for all of maybe 20 minutes and the rest is just a slightly-worse version of the first film as he tries to kill the dad of the guy he killed by slow-electrocution in the first movie.

The third one is a huge clusterfuck mess. It's like a dad-fantasy fever dream. That Neeson gets off scott-free at the end despite all of the things he did to evade capture and the fact that he basically took the law into his own hands would all add up to more jail time than if he had actually killed his wife for realsies. Also that part about the bagels was some of the most retarded shit I've ever heard recorded to film. Whoever wrote that should be ashamed.
