As far as magical girl shows go, I thought it was 
absolutely adorable...and all the Tenchi in-jokes 
make it definitely worthwhile. Plus, the 
character design is more reminiscent of the OVA, 
as opposed to the El Hazard-ish design in Shin 
TM. I can think of worse ways to spend 13 hours 
of your life ^_^

and c'mon, it's got Sasami-chan! What more could 
you ask for? (not that I'm biased or anything ^_^)
