A natural breakdown is:

• その = that (used before a noun)
• 映画 = movie / film
• は = topic marker
• とても = very
• いい = good
• と = marks the content of a thought
• 思います = think

So the structure is basically:

As for that movie, [it is very good] I think.

Japanese often puts the main verb at the end, so 思います comes last.

Because その is the form used before a noun.

In Japanese, demonstratives come in matching sets:

• これ / この = this
• それ / その = that
• あれ / あの = that over there

Use:

• それ by itself = that
• その + noun = that + noun

So:

• それ = that
• その映画 = that movie

You cannot normally say それ映画.

は marks the topic of the sentence.

In その映画は, the speaker is saying: as for that movie...

Then the rest of the sentence gives the speaker’s opinion about it:

• その映画は = as for that movie
• とてもいいと思います = I think it is very good

A topic is not always exactly the same as the grammatical subject in English, so it helps to think of は as setting the thing you are talking about.

いい is the normal everyday form meaning good.

Historically, it comes from よい, and よい still exists, but いい is much more common in ordinary speech.

So both can mean good, but:

• いい = more common in daily conversation
• よい = sometimes sounds a bit more formal, written, or careful

In this sentence, いい is the most natural choice.

Because before と思います, Japanese usually uses the plain form of the quoted statement.

So:

• その映画はとてもいいです。 = That movie is very good.
• その映画はとてもいいと思います。 = I think that movie is very good.

Not:

• その映画はとてもいいですと思います ✘

This is a very common pattern in Japanese:

• plain statement + と
  • thinking/saying verb

Examples:

• おもしろいと思います = I think it is interesting
• 高いと思います = I think it is expensive

Here, と marks what is being thought.

You can think of it as introducing the content of the thought:

• とてもいい = very good
• とてもいいと = that it is very good
• とてもいいと思います = I think that it is very good

With verbs like 思う (to think) and 言う (to say), と often marks the quoted or reported content.

Because Japanese is usually a verb-final language.

The main verb of the sentence often comes last. In this sentence, the main action is thinking, so 思います goes at the end.

English:

• I think [that movie is very good].

Japanese:

• [That movie is very good] I think.

This word order is very normal in Japanese.

Both are possible, but they feel a little different.

• その映画はとてもいいです。 = That movie is very good.
• その映画はとてもいいと思います。 = I think that movie is very good.

Using と思います makes the statement sound more like a personal opinion and often a bit softer or less direct.

This is very common in Japanese, especially when giving opinions politely.

Yes, in English you would normally say I think..., but in Japanese the subject is often omitted when it is obvious from context.

So 思います here naturally implies:

• I think

Japanese often leaves out words like 私 when they are understood.

A fuller sentence could be:

• 私はその映画はとてもいいと思います。

But in normal conversation, 私は is often unnecessary.

Because とても is an adverb, and it modifies the adjective いい.

So:

• とても = very
• いい = good
• とてもいい = very good

This is similar to English, where very comes before good.

No. They are usually added only for learners.

Normally, this sentence is written as:

その映画はとてもいいと思います。

Japanese is ordinarily written without spaces between words.

Textbooks and beginner materials often insert spaces to make it easier to see the parts of the sentence.

Yes. For example:

• この映画はとてもいいと思います。 = I think this movie is very good.
• あの映画はとてもいいと思います。 = I think that movie over there / that movie we both know is very good.

The difference is in the demonstrative:

• この = this
• その = that
• あの = that over there / that one known to both speaker and listener

Learning these こ・そ・あ words is very important in Japanese.
