The show was better than I thought it would be.
How can we translate this into German? I think
(a) Die Aufführung war besser als ich dachte.
already captures the meaning of the sentence, but it leaves out the part "it would be" at the end. How can we insert that part? Something like
(b) Die Aufführung war besser als ich dachte sie wäre.
doesn't sound right.
