I didn't read the books.
Prisoner of Azkaban— and to a lesser extent Chamber of Secrets and Goblet of Fire— had a necessary mix of whimsy, humor, color, and charm, and also seriousness/darkness. The series should have stayed that way.
But then first they sucked out the literal color, then the literal light, then the happiness out of the movies. By the time I saw the earliest part of Deathly Hollows, I just stopped caring. Every moment became joyless and hard to watch.
If there's no more discovery of the whimsy of the wizarding world, no more wonderment, no more seeing characters be just plain likeable, why do I care anymore? The series slowly became about friends being jealous and petty, people being double-agents, and about death and loss.
I had to read a summary of the events of Deathly Hollows, because I couldn't subject myself to 4 more hours of misery after the latter two-thirds of Half-Blood Prince. Now I'm just going to enjoy the full LEGO Harry Potter collection game.
Yeah, I am not going to "grow the fuck up"
I have no objection to people who dislike how the tone changed once they have watched the entire series
But if you bail out before the end -- if you bail out before you get a true understanding of what the series is really about (an analogy of World War II in the magical world, where the muggle born witches & wizard are the Jews and the purebloods & Death Eaters are the Nazis) -- then I have no sympathy for you at all.
Also, if you didn't do at least a little research into the series before you started watching it -- if you go into it thinking "this will be a happy, fluffy series about a boy who goes to magical school and nothing bad happens to him" then quite honestly I have very little sympathy for you as well. The entire series is 30 years old -- if you don't know Harry Potter is about a war (a war where people will die and a war where people will suffer) then quite frankly that is on you and really you have no one else to blame.
My boss, the first time he watched "The Sound of Music" expressed great surprise that there were Nazis in it, which really made my go "what the fuck did you expect -- it's set during the invasion of Austria in World War II". But apparently he didn't bother to do any investigation or research, and was quite upset by the Nazis. And I had no sympathy for him either.
So yeah -- really you brought this on yourself.
I could not even imagine saying something as stupid as this. "You didn't truly understand it because you skimmed the last 4 of the 20 hours, therefore your dislike is invalid" is truly a smooth-brain take. I wonder what other stupid shit you spend your life saying.
That wasn't my point, but whatever
