הבמאית של הסדרה הזאת אומרת שהמסר חשוב לה יותר מהסיום.

Yes. במאית is the feminine form of director. The masculine form is במאי.

• במאי = male director
• במאית = female director

The ה־ at the beginning is the definite article the, so:

• במאית = a female director
• הבמאית = the female director

So this sentence is specifically talking about a woman.

In Hebrew, demonstratives like this usually come after the noun.

So:

• הסדרה הזאת = this series
• literally: the series this

This is normal Hebrew word order.

You will often see:

• הספר הזה = this book
• הילדה הזאת = this girl
• הסרט הזה = this movie

Also notice that the noun is usually definite too, so Hebrew uses both:

• הסדרה הזאת not just
• סדרה הזאת

של means of or sometimes belonging to.

So:

• הבמאית של הסדרה הזאת = the director of this series

This is a very common Hebrew way to show possession or relationship:

• הבית של דני = Danny’s house
• השם של הסרט = the name of the movie
• המורה של הילד = the child’s teacher

So here, של הסדרה הזאת tells you which director: the one associated with this series.

Because the subject is feminine singular: הבמאית.

In the present tense, Hebrew verbs agree with the subject in gender and number. So:

• הוא אומר = he says
• היא אומרת = she says

Since הבמאית is feminine, the verb is אומרת.

The prefix ש־ means that.

So:

• אומרת שהמסר חשוב לה = she says that the message is important to her

This ש־ introduces a subordinate clause, just like that in English.

More examples:

• אני חושב שהוא צודק = I think that he is right
• היא יודעת שהיום יום שישי = she knows that today is Friday

In everyday Hebrew, ש־ is extremely common.

Because חשוב agrees with המסר, and מסר is masculine.

Hebrew adjectives usually agree with the noun they describe in gender and number.

• מסר is masculine singular
• so the adjective is חשוב

Compare:

• מסר חשוב = an important message
• סיבה חשובה = an important reason

Even though the director is female, חשוב is not describing her. It is describing המסר.

לה means to her.

In Hebrew, the idea important to someone is often expressed like this:

• חשוב לי = important to me
• חשוב לך = important to you
• חשוב לו = important to him
• חשוב לה = important to her

So:

• המסר חשוב לה = the message is important to her

This is a very common structure in Hebrew.

יותר means more.

So:

• יותר מהסיום = more than the ending

The full part:

• המסר חשוב לה יותר מהסיום means
• the message is more important to her than the ending

Hebrew often builds comparisons with:

• יותר מ־ = more than

Examples:

• זה יותר גדול = this is bigger / more big
• הספר הזה מעניין יותר מהספר ההוא = this book is more interesting than that book

Because מ־ is the preposition from / than here, and it attaches directly to the next word.

In comparisons, יותר מ־ means more than.

So:

• מ + הסיום becomes מהסיום

This is a very normal contraction in Hebrew.

You may also learn the fuller form מן, but in everyday Hebrew מ־ is much more common.

So these all relate:

• יותר מהסיום = more than the ending
• יותר מהספר הזה = more than this book
• יותר מהכל = more than everything

סיום can mean ending, end, or conclusion, depending on context.

In this sentence, the ending is the most natural translation, because we are talking about a series.

So:

• הסיום = the ending

If the context were different, it could also refer more generally to the end of something.

Hebrew word order is fairly flexible, but the version here is the most neutral and natural.

• המסר חשוב לה יותר מהסיום = the message is more important to her than the ending

A simple way to understand it is:

• המסר = the message
• חשוב לה = is important to her
• יותר מהסיום = more than the ending

Other word orders are sometimes possible for emphasis, but this one is standard and smooth.

Sometimes, yes. In modern Hebrew, both הזה / הזאת and הזה / הזו may be heard, depending on register and style.

For feminine singular:

• הסדרה הזאת = very standard
• הסדרה הזו = also common, especially in spoken Hebrew

For a learner, הסדרה הזאת is an excellent form to use and recognize.

Yes. אומרת is present tense: says or is saying, depending on context.

Hebrew present tense often covers both simple present and present continuous, depending on the situation.

So:

• הבמאית ... אומרת can mean the director says or
• the director is saying

In this sentence, says is the most natural English choice.
