I guess I never realized how much the second CCS movie and Tsubasa were alike until the second time I watched it. The moive itself is probably more similar to Tsubasa than the entire CCS series is. The premise of "emotion" "love" and "loss" are extremely prevalent in both. Also, Tsubasa is all about the Syaoran x Sakura relationship as is this movie, following the development of the 70 episode series. I definitely recommend watching this movie and the CCS series if you love Tsubasa, and vice versa. Watching one will teach you about the main characters in the other as well.
