"Ron doesn't deserve Hermione, he's too stupid/immature for her, she can do better!"
I've seen this one a lot... Something I noticed is, he seems to be made out to be a lot dumber in the movies than he is in the books. I mean, he wasn't the brightest boy, and he was goofy and more laid back, but he still knew stuff, and he wasn't a complete dumbass. Heck, he knew stuff about the wizarding world that Hermione didn't, if for no other reason than he was raised in it and she wasn't. I recently re-read the first two books and found a lot of things that he explained, that were explained by other characters in the movies.
On another note, that's a very shallow way of looking at it. Is she supposed to find someone who's just a male version of her, super-smart and uptight?
If we're to believe they are real, human characters, then we have to believe they don't fall in love based on logic, because when has love ever been logical?
Ugh... people, wanting their perfect characters and pairings... how boring...
