Cảnh này xấu.

In Vietnamese, demonstratives like này (this) usually come after the noun.

So:

• cảnh này = this scene
• literally: scene this

This is normal Vietnamese word order. English says this scene, but Vietnamese usually says scene this.

You can compare:

• nhà này = this house
• người này = this person
• cảnh này = this scene

Vietnamese often does not use a word like English is when an adjective is the predicate.

So:

• Cảnh này xấu literally works like This scene ugly
• natural English: This scene is ugly / bad

The adjective xấu can directly describe the subject without needing a copula.

This is very common in Vietnamese:

• Trời đẹp = The weather is nice
• Nhà lớn = The house is big
• Cảnh này xấu = This scene is ugly / bad

Cảnh is a flexible word. Depending on context, it can mean:

• scene
• view
• sight
• situation
• spectacle

So Cảnh này xấu could mean slightly different things depending on what people are talking about:

• a visual scene in a movie
• a view or sight in front of you
• a situation that looks unpleasant or disgraceful

If the meaning was already given to you, context is what tells you which sense of cảnh is intended.

Xấu often means:

• ugly
• bad-looking
• unsightly
• sometimes bad in a broader sense

With cảnh, it can describe something visually unattractive, but it can also suggest something unpleasant, shameful, or undesirable.

So depending on context, xấu could feel like:

• ugly
• bad
• unpleasant
• disgraceful

For example, if talking about a landscape, xấu may mean ugly-looking.
If talking about a social situation, it may feel more like bad or embarrassing.

Yes. It is a complete and natural Vietnamese sentence.

It has:

• Cảnh này = the subject, this scene / this situation
• xấu = the predicate adjective, ugly / bad

Vietnamese often allows very short sentences like this, especially in speech.

Not necessarily. Cảnh này is perfectly fine.

You may also hear:

• Cái cảnh này xấu

Adding cái can make the noun phrase sound more concrete, colloquial, or emotionally pointed, depending on context. But it is not required here.

So:

• Cảnh này xấu = neutral, normal
• Cái cảnh này xấu = also possible, sometimes more emphatic or more speech-like

Normally, no. Là is not used here.

When Vietnamese uses an adjective directly as the predicate, you usually do not insert là.

So:

• Cảnh này xấu = correct
• Cảnh này là xấu = unnatural in normal Vietnamese

Là is more commonly used when linking one noun to another, such as:

• Đây là cảnh cuối = This is the final scene

But with adjectives like xấu, đẹp, lớn, nhỏ, you usually leave out là.

In a sentence like this, yes, that is the basic pattern:

• cảnh này = this scene
• xấu = ugly / bad

So the structure is:

• noun + demonstrative + adjective

More broadly, the sentence pattern is:

• subject + predicate

Here the subject is cảnh này, and the predicate is xấu.

You can make similar sentences:

• Nhà này đẹp = This house is beautiful
• Phim này hay = This movie is good
• Người này cao = This person is tall

Yes. Vietnamese has several demonstratives.

For example:

• cảnh này = this scene
• cảnh đó = that scene
• cảnh kia = that scene over there

Very roughly:

• này = this, near the speaker
• đó/đấy = that
• kia = that over there, farther away or more clearly separated

So the choice depends on distance, context, and speaking style.

Sometimes, yes. Xấu can sound fairly direct.

If you want to soften it, Vietnamese often uses a negative of a positive adjective instead:

• Cảnh này không đẹp = This scene is not beautiful

That can sound less harsh than:

• Cảnh này xấu = This scene is ugly / bad

So if you are criticizing appearance and want to sound softer, không đẹp is often a good choice.

It can, but context matters.

If you specifically mean scenery or landscape, Vietnamese often uses:

• phong cảnh = scenery, landscape

So you might also hear:

• Phong cảnh này xấu = This scenery is ugly

By contrast, cảnh by itself is broader and can mean:

• scene
• view
• situation
• spectacle

So cảnh is correct, but phong cảnh is more specific if you mean natural scenery or landscape.
