I don´t recommend this film to young people who was are beginning their professional careers because it could make them believe that to get to be the best in their professions, they have to renounce to their personal lives. It doesn´t mind matter if they enjoy with that it or not and, if it is necessary, they must hurt their themselves and let their mentors humiliate them and attack them without any reason instead of teaching them how make to perfect their work. (In this case, perfect is a verb and the stress is on the second syllable. To "per-'fect" is to "make better.") correctly. The message that the film tries to transmit that film convey is: If you get want to be the best and be remembered for that, everything (You could also use "anything" here.) is justified.

I don´t share the opinion of agree with the director's opinion; I think that the best way to get to be the best in your profession is to enjoy your job, work ing hard, and be ing a equilibrate balanced person.

Your vocabulary is very good. I have not seen this film but I agree with you!

"Whiplash"

The Last Saturday it was a snowing so my boyfriend and me I decided to go to the cinema to see "Whiplash." (Many people use italics or quotation marks for titles. Also, in America, quotation marks ["] go outside of punctuation.) We chose that film for two reasons: first, ly because we have had read a lot of good reviews about it and the second, reason was that my boyfriend is a professional drummer. and The film is about a young drummer who wanted to be remembered like as the best musician in history, so he decided to study in at the best musical academy of EEUU in the US, with a very exigent demanding teacher. (Exigent may be used here but it is not natural. Most people say "demanding.") 

In summary, we don´t like the film and I would like to explain why.

My boyfriend found a lot of musical incongruities (Many people would say "contradictions" here.) which obviously I didn´t realize recognize. I only could only notice that, for the director, the faster you play the drums, the better musician you are.
But As for me, a person who have has been a teacher for some years, it worried seemed to me that the director confused to be being an exigent (or "demanding") teacher with to be being an abuser and finding a the way to justify it. If the main character's hand got bloody  ed due to the long time he pass practiced,  ing is it was because he doesn´t didn't have good technique and not because of the effort.  If he doesn´t get to didn't play in the correct “tempo” it was because nobody have teach had taught him what it is was.
