Why are you reading my review when you could be better spending your time watching this show?
If you are reading, it means you're hesitant: please don't be. Don Quixote is a fantastic watch, wonderfully acted, well directed, full of sweetness and serious issues treated with a light touch which is neither shallow nor melodramatic.
But most of all, you will laugh. A lot. Loud.

Yes, I'm a fan of Matsuda Shota and started watching because of him. I had been waiting for his next drama with a passion after Liar Game and prepared myself to be swept away by his very natural charm - and looks, I won't deny it.
He did not disappoint me one bit. He's outstanding: infuriating but incredibly sweet, hilarious but bossy, dense but clever in a very down-to-earth way and just as crazy as the famous hero created by the pen of Cervantes.
But a Don Quixote review would be incomplete and totally unfair without including Sancho Panza in it, brilliantly portrayed here by Katsumi Takahashi. As the synopsis explains, there's a soul switch involved in this drama, so that we see the two actors suddenly changing attitude, accent, facial expressions. The attentive viewer won't fail to recognize the ability of these two actors to wear the clothes of the other. The result is comic and endearing. Takahashi and Matsuda form an unforgettable duo.
All the secondary characters do a splendid job. The Yakuza's family is so improbable you can't help but laugh out loud and all the staff of the child consultation centre grows in depth and characterization.
And then there's the children. Japanese have a true knack of telling children stories, in my opinion. The fact that these kids are all incredibly cute and most of the time talented helps.

I loved the music too. It's in Spanish, as required by the title, and the contrast between the Spanish sunny rhythm and the Japanese architecture and landscapes is so sharp it's brilliant. I also loved the open credit tune with the children drawings, I thought it was a very cute touch.

I will rewatch this drama. Soon enough. I will marathon a second time through it and no doubt be left with the same huge grin on my face.
Highly recommended.
