The Has Fallen Trilogy with King Leonidas is criminally underrated and built around his trusted relationship with President Freeman which really helps some of the story telling.

That said, the 3rd entry suffers from some bad cgi and obvious casting (you know who the bad guys are and just wait for it to come together). However, those are nitpicks. Die Hard will forever be the greatest action movie and best Christmas movie, but there is a good argument that Has Fallen is superior.
