Ron Weasley is not an unattractive, bumbling oaf. Thanks a lot, stupid movies (actually it seemed that in the seventh book in a few parts, JKR was influenced by the previous movies). He has five brilliant and gifted older brothers, a famous best friend, and his younger sister is the family baby and only girl (a combination for lots of attention if anything is). He is also a preteen/teenager. Each of these things alone is enough to make him insecure, but together?
And he doesn’t look like Rupert Grint. I had wished that they had cast Domhnall Gleeson (I said that before he got famous), but he would have been too old, and really almost anyone else would have been better, Grint is decidedly unattractive. Ron may not have been handsome like Bill, but that does not mean he had to be ugly.
Harry and Ron both have the genetic capacity (just like Hermione) to be brilliant. They were a rather lazy, but they were just as smart, if not smarter than Hermione. Their OWL grades were lower than hers but barely (and for Harry one was higher), and she spent more time studying. Intelligence is brain capacity not outcome
Anyway, back to ruining Ron. After watching the third movie one time, I consulted the book during the confrontation scene among the Marauders and the Trio, and discovered one of Ron’s lines in the book was given to Hermione in the movie which made him look like a cowering idiot.
Which love brings us to the biggest movie crime. Because Ron loved Hermione he was emotionally tortured (as was Harry, he cared too) while she was physically tortured. Ron was not a calm person, panic was usually his default. Does emptily staring as he did in the movie really match his personality? I mean Harry was pretty upset too; what decent person would be thrilled hearing anyone, much less a friend, tortured? But for Ron, that was his beloved. I am still stunned by the insensitivity of that scene in the movie.
