What I'm talking about: a casesituation when a TV Series that is based on a book, is better than athe book itself.

A couple of years ago I watched a TV Series "Unorthodox", and do you know what?

"you know what?" is more colloquial - you could also say "and what do you know?"

At the end of the last episodseason finale, I cried.

"series finale" is how we refer to the last episode of a series and "season finale" is the last episode of a season

Then, I bought athe book and I thought that the book is moreit was "calmer" or "flatter" except for the scenes when the main character describesd her period of growing likegrowth as a woman.

Esther wasn't a typical Jewish woman, but when her family chose a groom for her, she didn't stand any chance tocouldn't decline this "deal".

After that, all the relatives started to pressure the "newborn" couple with a question: "Where isn will you have your first child?".

It took a couple of years and tens ofmany doctors whenbefore they became parents.

We often use "hundreds of __" or "dozens of __" but rarely "tens of __". So here, you could also say "dozens of doctors"

AllDuring this time, Esther didn't understand why she must dress closonservative closthes, why she can no't study at the university, and a huge bunchcontinuing list of things that she can no't do.

I don't want to tell you the end of this story because you will lose the unexpected effecspoil the ending so you can enjoy the twist if you decide to watch the TV Sseries.

"the twist" is how we describe an unexpected ending or development of a story.
You don't always have to say "TV series" - you can just say "series" or "TV show"

The end ofing in the book and the TV Series are different, but I prefer the second one.is different from the TV Series, but in my opinion, the TV adaptation is better

This case is definitely not the only one.

Correct; you may consider rearranging it to another place in the passage though. When the reader is first greeted with this sentence, they can potentially get confused due to the lack of context.

What I'm talking about: aThe case whenre a TV Series that is based on a book, is better than athe book.

Correct; you may want to delete the comma. Rewritten so it’s more concise.

While the original sentence would work perfectly fine in a spoken context, I have abridged it to sound more formal.

Then I bought a book and I thoughnd read the book, only to find out that the book isfell more "calm" or "flat" except for the scenes whenre the main character describes her period of growing like a womantells us more about her growth.

I expanded this sentence to give the paragraph a bit more rhythm, considering the adjacent sentences were all fairly short.

She did big workfought valiantly to protect her own interests and the rights to choose her own path.

The main actress who performed Esther did her workportraying Esther delivered perfectly.

Through the screen, I "read" all her emotions and feelings.

Stylistic revisions to sound more hyperbolic.
