Let's start with that I've seen a lot. It's all public. In the most cases meta's score given to a movie shows a better rating, a more realistic one compared to imdb.

I've seen 1917, I was sick of that people don't even know what cinematography is. The whole movie was made like "Rope" except that Rope had an amazingly interesting story. 1917 had nothing in it. Paths of Glory was in many terms a lot more realistic. Long story short, I didn't like 1917 at all. I had no idea why it was even nominated.

Then I saw the Marriage Story. As soon as I realised Adam Driver is in it (Star Wars guy), I just wanted to not like the movie because I don't like the new SW movies at all. Then it turned out it was amazing. He was very good, the movie was very good. I liked The Irishman too but the Marriage Story was superior.

Then came the awards and Parasite won. I saw it has a score of 8.6 and I know the director. He did a crime movie which I liked (Memories of a Murder). That one was very good.

So I just watched Parasite too.

It was interesting, but maybe I've seen too many actually good movies, so I do not blow my mind just like that.

The characters were ok and maybe that's all. The story was just interesting. There was nothing special about it. It was an original story, but it won't make it good. It has nothing to tell us. It's pretty much like a half written mess. If somebody works for me for years, I won't fire him/her just because a tale someone told me. I would atleast question the worker. Atleast! At this point the movie was very unrealistic.

The smell factor. We can't smell it :) But all that food as whiskey on that table has a strong smell. You can clearly see under the table. I just had no idea how is that realistic.. They were all given good wages and still they didn't take a shower or anything like that. They did all smell bad.. Sooo unrealistic and because of it the father's motivation made absolute no sense. No sense at all. Especially in that situation.

It felt like they had to end the story somehow and they chose this way for some reason.

Other factors of the movie are no special neither.

Roma stands on 7.7 and is by far better in every aspect.

Currently I've rated over 2500 movies, I write scripts, I'm working on to direct one of my works myself and I have to tell you that this movie was just OK and I have really no idea why would anyone give it a score of 8 or higher. If I would write and direct a movie like this, I would be not satisfied. Not at all. For me it was 6.5 as it was interesting. Also it's genre is drama/thriller. There was not a single second in the movie that was comedic!
