Twas OK.
Lois gets 3 moments where she uses her strength:
First, when she describes her new power - she lifts a refridgerator.
Second, when she is stuck in traffic, she lifts the car and runs down the street.
And finally, she punches through a large door in City Hall.
Her power level is as equal as it was in "Lethal Weapons," where Lois learns Tae Jitsu and takes on about 15 people at once - including General Zod, Ursa, and Non (She dispatches them faster than Superman does! 8) ).
