I really enjoyed Bourdain's documentary about El Bulli,Decoding Ferran Adria: Hosted by Anthony Bourdain (and the episode of No Reservations with Ferran Adria), and in those you really got to see what cooking and eating at El Bulli was like. I also enjoyed Lisa Abend's book The Sorcerer's Apprentices: A Season in the Kitchen at Ferran Adrià's elBulli. This movie, however, was much less interesting to watch.
The movie is 1hr 50mins long, and all dialogue is in Catalan, Spanish, or French, with English subtitles. The first half of the movie is almost all video of Ferran's sous-chefs working in the lab. There is no narration at all, very little cooking, and it is somewhat tedious to watch. Yes, it is interesting to see what they do, but most of the time it is unclear exactly what they are doing and what ingredients they are using. Still, it is quite amazing how meticulous they are in the lab. The second half takes place in the restaurant, where we see them set up for the season. Again, it is usually not clear what exactly they are doing. You might see them making some cool looking dishes, but the viewer has no idea what they are. At one point we watch Ferran eat his own meal, but for the most part, we do not know what the dishes are or how they taste! We just see him make notes quietly. Pretty dull.
If you are really into El Bulli, this is worth watching for the behind-the-scenes look, but in the end it is just ok. Could have been great, with lots of narration and better editing.
