Questions & Answers about kono eiga wa omoshirokunai desu.

What does この mean in this sentence?

この is a demonstrative adjective meaning “this.” It comes directly before the noun 映画 to specify “this movie.”

Why is the particle は used after 映画 instead of が?

は marks the topic (“As for this movie…”). It sets up what you’re talking about. が would mark the subject or emphasize it, but here you’re simply stating your opinion about the topic.

How do you form the negative of the i-adjective 面白い?

1. Drop the final い from 面白い.
2. Add くない to get the plain negative: 面白くない.
3. To make it polite, append です: 面白くないです.

Why is there a です at the end if the adjective is already negative?

です is the polite copula. It doesn’t change the negative meaning; it simply makes the whole sentence polite, much like adding “is” in English courtesy formulas.

What’s a more formal way to say “not interesting” instead of 面白くないです?

You can use the adjective stem plus the polite negative copula ありません:
面白くありません
This is more formal and can sound more business-like.

How would you say the sentence in casual (plain) speech?

Drop the polite です entirely:
この映画は面白くない。

Why are there spaces between words in the example?

Japanese is normally written without spaces. Here, spaces separate elements (この｜映画｜は｜面白くない｜です) to help learners see each word or particle clearly.
