No crossovers or references to other dc IPs makes the show lackluster in my opinion especially since that's how the started and considering it takes place at a point the earth should be riddled with heros. Also has the lamest iteration of Lex Luther. I thought Supergirl was the best of the most recent live action shows dc produced on the cw, but Peacemaker is by far DCs greatest show they have since they passed on Homelander.
