Some thoughts on, or tangents from, Buffy Episode One:

(And PLEASE PLEASE PLEASE DO NOT PUT ANY SPOILERS IN THE COMMENTS, THANK YOU.) (Of course, be warned, I'll spoil anything I want to.)(No, not really, I'll keep things vague.)

( Mark Twainishness )

( Sailor Moon )

( Hero as (non)loner )

( Who is that masked man? )

Buffy Season One Episode Two: Suspension Of Disbelief Not Fully Achieved

(1) Why doesn't Buffy get more scared?
(2) Why do she and her gang need to keep this all a secret? (Still not explained.)
(3) Absence of cops not yet explained either. Obviously Buffy and crew won't call 'em, but kids who are being attacked in dance clubs would. (And hey, this was maybe 12 years ago, but cell phones existed, and so did worried parents.)
(4) Don't, like, any other students use the library?
(5) Angel WTF?

(Please, no spoilers in comments.)
