Harry Potter TV Series

Some of y’all have never been to the country where you’ll regularly see fine *** women with complete doofus men
Hermione and Ron make sense- he is a source of goofiness and comfort (2 things she lacks entirely) and of course someone she can ‘fix’
Harry doesn’t need a GF, he needs a peer - he can’t get comfortable, he needs to be pushed/challnged
As a relationship H/H compliment what the other is already good at
Hermione and Ron make each other better
Ginny offers Harry a more comforting version of Hermione, but with the added sense of home/family that Harry always lacked and yearned for

I have been to America.

You can create justifications all you want, but the fact is that Ron is an idiot and nobody as smart as Hermoine would want to deal with him long term. If they make sense as a couple, then it's a couple that gets divorced in a few years realizing that neither is fit for the other and they actually hold each other back from being who they are.

Harry and Hermoine compliment each other. Hermoine is brilliant but lacks confidence and a real sense of adventure. Harry comes close to her in intellect, occasionally challenging her, and gives her the courage, confidence, and sense of adventure that she needs to be great.

Beyond all that Harry and Ginny just make no sense. They aren't similar and he's not the type of guy she had gone for in the past. The only way it could make sense is that she fell for him after he saved her life and he feels obligated to continue protecting her. She want to be saved and he needs to save people. But, that co-dependent basis of relationship is doomed to fail or at best result in a cold, loveless marriage.
