I started watching this the other day. I was curious if it was just nostalgia for a lame girls' show, or if it was any good.
I'm enjoying it. I'm the simple sort of person that just wants to know what's next, so the monster of the week format is fine with me.
Sakura is cute. The cards are cool. Tomoyo isn't that interesting to me, but she's extremely similar to Kozue from the 2003 VN "Snow Sakura". It isn't surprising, but it was just kind of neat to see what might be the source of inspiration for the character.
