Usually I don't read a book before to watching the movie, but two years ago I didmade an exception with "The Martian" ofby Andy Weir.

You can also say "made an exception for," which sounds like you were eager to read the book before watching the movie. When you say "made an exception with," it sounds more like you didn't plan to read the book before watching the movie, but the chance to read it just came up.

Before Covid, in theOVID, in Barcelona's libraries, in the hall always there was always an interchange table, so if you haved a book you had already read, and no havet enough space at home, you could go and leave it in that table.

Lots of people don't capitalize COVID, but it is an acronym so it should be capitalized in formal writing.

You awere free to catchtake any book from that table too.

It iwas a great idea.

Your sentence is technically correct, but the jump in tenses is awkward.

Well, aone day I found this book, "The Martian," in English.

I put another comma after "The Martian" because it is a nonessential clause. You can remove the phrase and still have the sentence make sense.
People follow different rules with titles of books. The formal rule is that you should italicize or underline the titles of long, stand-alone works, such as books or newspapers. The titles of shorter works, such as chapters or articles, should go in quotations. However, in informal writing, lots of people use quotation marks (or nothing at all) for book or movie titles. The important part is to be consistent.

I was in delight with each page I was reading.

The sentence was grammatically okay but awkward.

So, I was reading at all times I whichwhenever I could.

Furthermore, I found a page in internetwebsite with a detailed map of mMarts, so I could to follow the day -to -day of the astronaut Mark Watney, and see his journey about during the 384 pages of the book.

I liked it so much that I bought the movie ion DVD.

HowAs you can imagine, despite it be aing great film, and the good work of Matt Damon, andin the end I had the feeling that in the movie hasd been missing the half of the book.

The comma after "film" is unnecessary. One of the two sentences below (each with a minor change) would be better:

As you can imagine, despite it being great film and the good work of Matt Damon, in the end I had the feeling that the movie had been missing half of the book.
As you can imagine, despite it being great film, and despite the good work of Matt Damon, in the end I had the feeling that the movie had been missing half of the book.

For all thisAll in all, this is one of the books that I have liked most.

"For all this" doesn't seem quite right. The appropriate clause depends on what you're trying to say. Below are some suggestions:

"Regardless" or "Despite this": Even though I did not like the movie as much
"All in all": When I consider all aspects
