The Matrix Reloaded

"The" is also part of the movie title.

To be honest, I don't remember which one I watched 2 days ago (and I also forgot to write a review here, sorry :() ¶
).¶
¶
The movie starteds in the Nebuchadnezzar, it is the ship of our (main) characters.

Generally, when describing story plots, we will use the present tense ("starts").

Neo is definitely another person,something else: he's stronger, more intelligent and obviously looks different, like morehe's wiser or something like that.

"Something else" can be used to describe someone or something that is exceptional in some way.

We also can watch tolook at Trinity, she's flexwearing a black outfit and it's so hot!

(1) "Watch to" is not a collocation we use here.
(2) I'm not too sure what "flexing" is supposed to mean in this context. I just replaced it with "wearing".

:) bBut in the first scene that we can seewhere we are introduced to her, she dies because she's fighting against an agent. (tThe agents are like machines and they're the strongest things in the Matrix).)

(1) The first word of the sentence should be capitalised.
(2) I rephrased your sentence slightly to make it sound more natural.
(3) I decided to make everything in the parentheses their own sentence, because there's no need to fit everything in one sentence.
(4) "The agents" is plural, so you should "things" and not "thing".

After that, they arrived to at Zion, it is the only human city in (the year) 2999.

(1) The phrase is "arrive at (a destination)".
(2) You can consider clarifying that "2999" refers to the year.

They have a problem,: the sentinels (they're big machines that couldan destroy Zion without problem) are going to Zion, and it isn't just one or two,; there are 250,000 Sentinels going to Zionof them.

(1) Keep the capitalisation of "sentinel" consistent. You should either capitalise every instance of the word, or not at all.
(2) I replaced the last part of the sentence with "of them" to avoid excessive repetition of "sentinel" and "going to Zion".

After all these action scenes, an Oracle speech, etc etc... Wwe arrive ato the last scene,. Neo, Trinity and Morpheus are intoside a big building looking for 'the door' (it is a white door where the Matrix creator of the Matrix is hidden), a lot of. Many action scenes has passed untilpass before they fouind the door, and only Neo, 'the chosen one', can go through the door, so Morpheus literally dissappear of ours from view.

(1) "We" shouldn't be capitalised because it's not the start of a new sentence.
(2) This original sentence is very lengthy and hard to read, so I've broken it into a few smaller ones.
(3) I've rephrased some parts of your writing so that it sounds more natural and fluent.
(4) The phrase is "disappear from (someone's) view". (You don't need the "our" here" though.)
(5) Again, note that when describing the plot of a story, we generally use the present tense.

Neo has a talk with the creator of the Matrix, and hewho literally puts two options ion the table.:

(1) It is not clear who "he" refers to here. I have rephrased the sentence to clarify this.
(2) I would merge this sentence with the one below. I have replaced the period with a colon to allow for this.

Trinity dies and nothing else happens OR Zion is destroyed and nothing else happens (I have memoriey issues, so these probably these weren't the exact options lmao).

The placement of "probably" is awkward.

Neo leaves the room and flies seeking tooff to find Trinity, but when he finally fouinds her, she already has a bullet in her body, after thatnd she dies... but a A couple of minutes later, Neo literally converts himself into a Machine and extracts the bullet ofut from Trinity's body, but she's still being die, butdead. But in another timeattempt, he tries to revive her with an electroic shock and she comes back to life.

(1) Again, this is a very lengthy sentence. It would be good to split it into smaller ones.
(2) I have again rephrased some parts of your writing so it sounds more fluent and natural.
(3) The phrase is "convert into (something)".
(4) The phrase is "extract (out) from".

After that, we have an scene outset outside of the Matrix where we can see the destroyuction of the Nebuchadnezzar, and our characters running for their lives.

(1) "Scene" does not begin with a vowel sound, so "an" is not used.
(2) "Destroy" is a verb. The noun would be "destruction".

After thatThen Neo destroys three Ssentinels using his powers and the movie finished with a big cartelption saying: 'To be continued' ¶
¶
Probably today I'll.¶
¶
I'll probably watch the next movie today.

(1) I replaced "after that" with "then", because you've already used "after that" in the previous sentence.
(2) Again, you can capitalised "sentinel" if you wish, but you must do this for all instances of the word. The first time you used "sentinel", it wasn't capitalised.
(3) It's been a while since I last watched the movie, but I don't remember there being a cartel... perhaps you meant "caption".
