Edgar Wright's films are always filled with interesting characters, and they band together to help the protagonist to archive their life goals. That is why we love his works so much.
On Baby Driver, the director/writer weaves a heist story with a teen romance story and the chemistry is exploding. With, again, a great soundtrack, cassette tapes, iPods, phrases from Monsters, Inc., the journey of Baby (Ansel Elgort) is a roller-coaster filled with gun fights and car chases. The story is well paced and full of gags (like Baby has to restart a song because the heist is delayed, or the post office preparation scene) and still deliver the tension of a heist film. Baby's boss Doc (Kevin Spacey) first looks cold and brutal, but when he tries to save Baby and Debora (Lily James) from harm, and uttered the words "I was in love once", that alone worth seeing the film.
Baby Driver is the third best Edgar Wright film (behind Scott Pilgrim Vs. The World and Shaun Of The Dead) because it is so funny and tensed and perfectly structured.
