Fanfic that loses it part of the way through. I was reading a really good Thor/Avengers fic - it was great, lots of plot twists, good fleshing out of characters, lovely PWP's thrown in for flavor, and the author either lost interest or gave up or something, because after 3 hours of reading I slam into "And Odin became cool, everyone is friends, they all lived HEA."
Whut? So all of a sudden Odin is a great dad (yeah, no - a lifetime of lies, favoritism, and teaching your kid to hate his own species, and it's suddenly rainbows and kitties and unicorns farting strawberry glitter? Uh, no), Loki's head is no longer a bag of cats, his banished kids are fine and well adjusted, earth forgives him for invading a major city, and every should go home and have cake.
