Tsubasa Reservoir Chronicle is one of CLAMP's most recent works to be made into an anime, and arguably the most popular in recent years. And why shouldn't it? For one, Tsubasa serves as a sort of "crossover series" for all other CLAMP works, and nearly every character is based off a previous incarnation in a different series. If you like CLAMP at all, your favorite CLAMP characters return in this series- including leads Syaoran and Sakura from Cardcaptor Sakura, Chi from Chobits, Mokona from Magic Knight Rayearth, and Yuko from xxxHOLIC. In fact, you could almost say CLAMP got lazy and didn't want to design any new characters. And yet, it works. Why? Tsubasa Chronicle is a "dimension-hopping" story, so while these characters look and sometimes act like their pervious incarnations, they are completely new characters (ex., Syaoran is a kind, nice guy now!).

Furthermore, this is a series for everyone. Like romance? You've got Syaoran's selfless devotion to Sakura, and the forgotten love she had for him. (so sad!) Like action? There's a fight/battle almost every episode. Like Fantasy? Fai's a wizard, and other characters later acquire magical powers for themselves. Already an anime fan? You could potentially call this InuYasha's storyline done right. And the best part? It's very, very clean. In fact, you could put this on TV as children's programming without much editing at all. This is a series for the whole family to enjoy. My sister and I watched this series together, and it made us both into even bigger anime fans than we were before.

Review
That being said, this series is far from perfect. While I would rate Season 1 (episodes 1-26) at a 7, but I would rate Season 2 (ep. 26-52) at a 5. While Season 1 had the fantastic manga to follow to create the plot, the second season surpassed where the manga was, leading to a large decline of story quality (basically, it was all filler-style world visits). And, due to the same problem with catching up to the source manga, this anime ends feeling unfinished, leaving you to either watch the Tokyo Revelations OVA next or just reading the manga for a complete ending. Personally, I recommend Season 1 and recommend just skipping Season 2.

Music Notes
Even if you disliked this series, the music is a must-listen. Yuki Kajiura's beautiful fantasy score is absolutely beautiful. "Song of Storm and Fire" will send chills down your spine, and "You are My Love" can bring you to tears. I LOVE THIS SOUNDTRACK.

Sub Vs. Dub
Both are fantastic, though I found Monica Rial's version of Sakura to be rather grating, and she can't sing very well. Other than that though, the dub is great. I advise you to just go with your usual preference.

Content Notes
There is very little to talk about in the area of content issues. The only really condemning thing in this series content-wise is in the theology section. The entire plot is centered around the use of magic. Fai is a wizard (though he never uses his power), and the group visit Yuko (known as the "Space-Time Witch") who gives them the magic to cross dimensions (a magic circle appears every single time they use it). Also, ghosts seem to be drawn to Princess Sakura, and communicate with her. In one world the group acquires magical abilities with animal-like forms, and in another they encounter two characters who Spoiler: end up becoming "gods" in their world (they are seen as golden idols).

Other than that though, this is a very family friendly series.
