For a while it reminded me of the period immediately before 1986 where writers and artists were merely going through the motions and producing some pretty mediocre fare.
Personally, I think some of the best Superman stories were told in this particular period before the reboot. Cary Bates and Elliot S! Maggin were both at the top of their games here, with one doing humorous and idiosyncratic stories and the other doing brief, plot-centered stories. Curt Swan, when he could get a good inker, was one of the more amazing artists on the stands. Mark Waid put in some amazing Superman backup stories, immediately after which, he decided to never be really excellent again. Marv Wolfman was...well...Wolfman, but even he couldn't sabotage Superman because he was carried on the shoulders of the giants at the Superman office, and Schwartz could say "no" to any bad idea.
Alan Moore's "Whatever Happened..." was an astonishing story. That ACTION COMICS story where he discovered a tenth planet where dinosaurs evolved is one of the most astonishing "Superman in Space" stories ever.
I don't understand why there was this perception that Superman was "getting tired" in the 1980s and so a reboot was inevitable. In fact, if anything, many, many plot threads were around at that point, which unfortunately, remain unaswered:
The Superman/Lana Lang relationship
Brainiac discovering that thing about the start of the universe
Superwoman and her future untold adventures
Lex's rankling for revenge at the destruction of Lexor
The Interstellar Zoo being rebuilt as a shrunken wilderness preserve
