Después de ver el tráiler, mi amiga dijo que el guion del drama parecía más original.

Because after a preposition such as de, Spanish normally uses the infinitive.

• después de ver = after seeing / after watching

You cannot say después de vio. If you want a full clause with a subject and a conjugated verb, you usually say después de que + verb:

• Después de que vimos el tráiler...

So después de + infinitive is a very common pattern.

Tráiler is a loanword used in Spain for a film trailer. The written accent shows that the stress falls on the first syllable: TRÁI-ler.

In Spain, tráiler is very common, especially in everyday speech. You may also see more native alternatives such as avance or tráiler de la película, depending on context.

Both are possible, but they do not sound exactly the same.

• mi amiga = my friend
• una amiga mía = a friend of mine

In this sentence, mi amiga is the most direct and natural option. Also, amiga tells you the friend is female. It does not tell you anything about the speaker’s gender.

Because Spanish often omits subject pronouns when they are clear from the verb form or the context.

• mi amiga dijo already tells us who did the speaking
• adding ella would usually be for emphasis, contrast, or clarification

So mi amiga dijo sounds more natural than mi amiga ella dijo.

Here que introduces reported speech or reported thought. It works like English that in a sentence such as:

• she said that the script seemed more original

In Spanish, this que is used very regularly after verbs like decir, pensar, creer, and saber when a new clause follows.

• dijo que...
• pensó que...
• creo que...

Because not all nouns ending in -a are feminine. Drama is a masculine noun:

• el drama

This is one of several common masculine nouns of Greek origin that end in -a, such as:

• el problema
• el sistema
• el tema

So the ending does not always determine the gender.

The current standard spelling recommended by the RAE is guion, without an accent mark.

Traditionally, many people wrote guión, and you may still see that form. But the modern standard treats guion as a monosyllable in spelling, so it is written without an accent.

For a learner, the safest standard form is:

• el guion

Parecía is the imperfect tense of parecer, and it presents the idea as an impression or appearance in the past, rather than as a single completed event.

• parecía más original = it seemed more original

Using parecía sounds natural when describing how something came across to someone. Pareció is also possible in some contexts, but it can sound more punctual or more tied to one specific moment of reaction.

In reported speech, dijo que parecía... is very natural because it presents what the script seemed like at that time.

Because parecer means to seem, not to be. The sentence is talking about an impression based on the trailer, not making a definite objective statement.

• parecía más original = it seemed more original
• era más original = it was more original

So parecer is a better choice when someone is judging from limited information, such as a trailer.

Yes. In Spanish, más + adjective is the normal way to make a comparison.

• más original = more original

Even if the thing being compared is not stated explicitly, Spanish often leaves it understood from context. It might mean:

• more original than she expected
• more original than another drama
• more original than the trailer suggested before

So the comparison is implicit.

Because original is describing the noun guion.

• el guion parecía más original

Here we need an adjective, because we are describing what the script was like. Originalmente is an adverb, so it would describe how something is done, not what something is like.

Compare:

• un guion original = an original script
• escribió originalmente = he/she wrote originally

Because original is an adjective that ends in a consonant, and many Spanish adjectives of that type have the same singular form for masculine and feminine.

• el guion original
• la historia original

The plural does change:

• los guiones originales
• las historias originales

So in the singular, original stays the same.

Yes. Tras can also mean after, so:

• Tras ver el tráiler...

is perfectly possible.

However, después de is usually more common and more neutral in everyday speech. Tras can sound a little more concise or slightly more formal, depending on context.
