"Should" have, but they didn't bother to actually build up the characters before trying to make an ensemble one, so of course it's not a huge spike.
My point is just that it's not doing terrible, and they could probably salvage it if they were willing to actually try.
Of course, I say that, but I guess there's probably a hard limit on how well it can do since the MCU has sucked all the air out of the room. I know personally even if the DCEU got good I wouldn't watch it just because it's too much to try to keep up with that on top of the MCU.
