Look, up in the sky — it’s the ratings!

The WB’s young Superman series Smallville leapt two networks with a single bound in its premiere episode Tuesday night, producing the best ratings for a debuting show in the “fifth network’s” history.

According to Nielsen Research, the hour-long premiere averaged a 6.7 rating and a 10 share, beating ABC’s Spin City (5.2/8) and the new Jason Alexander sitcom Bob Patterson (4.9/7) and also besting the final episode of Love Cruise: The Maiden Voyage on Fox (4.7/8).

The hour was won by CBS’s new drama The Guardian, which delivered a 10.5/16 and edged out NBC’s Frasier, which pulled a 10.0/15.”
