At first, there was only one person in attendance in that theater, then a couple came in.

After about ten minutes from the beginningafter the start of the movie, a group of four people entered the theater.

I need to focus on watching the sciene, listening their talkso the dialogue, and reading the subtitles.

I loved that movie.

I love Tim Baurton's films.

After finishing watching the movie, I finally realized that she was Wednesday Addams, in the Netflix drama, "Wednesday."

The movie looks like an hommage ofto the Addams Family.

The actors and actresses seemsed somehow familiar to me.

After Googling them, I found that the mother in "Home Alone" realso appeared in that film.

"Terma & Luise"'s" Terma (or Luise) was in it too.

There were so many interesting points in it, but I think it was very cool whomen Jenna Ortega pretended to be in her Halloween costume.

NOTE: The quotations are optional.

Or, if the only person in the theatre was you, then
"At first, I was the only one in the theater, but then a couple came in."

After about ten minutes from the beginning of the movie, a group of four people entered the theater.

This is fine. More concisely,

By itself, "theatre" is where you would watch a play or musical

For movies, you can say it like this:
"I went to the cinema to watch (the movie) Beetlejuice Beetlejuice"
"I went to the movies to watch Beetlejuice Beetlejuice"
"I went to the movie theatre to watch Beetlejuice Beetlejuice"

#1 is what I would consider most natural, at least in British English.

I went there aloneby myself.

The word "alone" technically means to go with nobody, but it is most commonly used in a negative way to suggest that you didn't want to be by yourself.

"None of my friends wanted to spend time with me, so I went to the cinema alone"

Other examples to illustrate the point:-
"I am all alone in this scary forest!"
"I wish I had a girlfriend so I wasn't alone all the time"

At first, there was only one attendance in that theater,other person there, but then a couple came in.

After about ten minutes from the beginning of the movieafter the movie had started, a group of four people also entered the theatere.

Do you mean 10 minutes prior to the movie starting? Or, 10 minutes after it had started?

Therefore, there were seven people in the endotal.

Or:
"In the end, there were seven people"

After finishing watching the movie, I finally realized that she wasplayed Wednesday Adams, in the Netflix drama, "Wednesday."

In this example, you don't need to have "finishing" -- we can simply say "after the movie".

You could maybe say:
"It was only after the movie that I realized she played Wednesday Adams in the Netflix drama "Wednesday".

The movie looks an hommage ofto the Adams Family.

The actors and actresses seemsed somehow familiar to me.

After Googling them, I found that one of the cast played the mother in "Home Alone" reappeared in that film.

"Terma & Luise"'s Terma (orThe actress who played Thelma from "Thelma & Louise)" was in it, too.

There were so many interesting points in itarts, but I think it was very cool whomen Jenna Ortega pretended to be in her Halloween costume.

"Interesting point" would be used about a discussion or a debate, not typically about a movie (unless the movie was particularly thought-provoking).

I don't understand the use of "pretended" here..?
