"Hitman 2" badly misses the mark. On the surface this promises to be an exciting action film, and indeed, with a markedly more linear script that played to that strength, it could have been. Regrettably, what you get instead is a moronic mashup of unfunny comedy, a half-baked family drama, a cheesy unlikable romance and a tiny dash of mostly fall flat action. Acting is fine, but really that's about all this…
