Clark Kent/Superman losing his powers is an old idea but losing his sight is a new one. We get our first sight of Clark wearing glasses, not only dark but also, as his vision returns, clear. His super-hearing increases, like Daredevil's.
We see Pete's mother and learn that she is a US Judge.
The conflict between the Luthors is never-ending and more interesting than Clark's and Lana's permanently off-off relationship. The latest twist is that Lex thinks it is an advantage for him that Lionel thinks he is weak. The Sullivans have fallen foul of Lionel.
It would be good to transport Lionel to a society where survival and success were entirely dependent not on competition or manipulation but entirely on cooperation.
