These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Legion
Complete Monster: Any Heavenly being, especially God, who isn't Michael. Instead of just mercifully making the planet explode, they resort to the underhanded method of bodysnatching human hosts to attack and murder other humans, some of these human suits being children. Also, if God is supposedly omnipotent, He would know about the redemptive traits of the humans in the diner, nevermind humans the world over, not to mention their selfless attempts to save each other, but ignores them in favor of continuing the genocide. If the sequel (if it's made) doesn't feature Charlie's baby overthrowing God following an epic Shut Up, Hannibal! / "The Reason You Suck" Speech, there will be Hell to pay.
Crowning Moment of Awesome: The above mentioned Bond One-Liner and its related incident for one, but there's also the preceding fight between Michael and Gabriel. Say what you will about the movie, that particular sequence was awesome.
Crowning Moment of Funny: Michael, after giving several characters a crash-course in automatic weapons usage, says if they get it wrong it might blow their hand off. Cue everyone looking at Percy, former military man, and his hook for a hand.
Percy: "What the Fuck ya'll lookin' at me for?"//
There's also the scene near the end where Audrey tries to shoot Gabriel in the face with a flare gun. She misses, but the flare bounces around for a bit and hits Gabriel anyway.
Genius Bonus: Michael going against God (and thus being called "rebel son" by Gabriel), in some countries Christianity got a bit muddled and so there are places where Michael is the one cast from heaven for mutiny.
Those tattoos Michael is covered in actually say things in Enochian, supposedly the language of the angels. According to Paul Bettany, one of them says, "If you're freeze-framing this film, you're really weird."
Narm: The whole damn film is filled with Narm and Narm Charm to the brim. Moviegoers went into hysterics after watching the trailer featuring that possessed old lady climbs up onto the ceiling. The whole scene with the granny qualifies, really. Hearing an old lady say "You and your fucking baby are going to burn" is hilarious, not scary. There's also the Creepy Child ("I just want to play with your baby") and Gabriel's chainsaw-mace.
Mileage does vary on Gabriel's mace. It's either ridiculous or So Cool It's Awesome.
Ships That Pass In The Night: Audrey/Gabriel is rather popular on Fanfiction.net and deviantART. This despite the fact that the two share exactly one scene, where she tries to strangle him and they both go through the windshield of a car at 90 miles an hour. Being an archangel, he lives. She...doesn't. It's nevertheless one of the most popular Het pairings in the fandom on both sites.
