THE worst superhero movies. PERIOD.

Same rules apply from this thread.

10 top lists, 10 top (worst) movies.

The Results ...

#1 Catwoman
#2 Batman & Robin
#3 Supergirl
#4 Fantastic Four 2015
#5 (Tie) Steel, Superman IV
#6 Electra
#7 Captain America 1990
#8 Green Lantern
#9 Howard the Duck
#10 Spawn

Catwoman really ran away with this. It was the only movie to appear in all ten lists and racked up the most points, by far. 
Batman & Robin was a "respectable" 2nd. It appeared in 9 lists and has a solid points lead over #3.
#3 thru #6 were all grouped fairly close together after a sizable drop in points from B&R. They appeared in the majority of the lists.
#7 thru #10 were also grouped close together following another sizable points drop from Electra. They only appeared in a few lists.

Seven DC
Four Marvel
One Other

No MCU movie made any list.
From the DCEU, BvS and Suicide Squad made a few lists, but couldn't crack the top ten.
Once again, it was looking like X-Men would be a no show but they managed to squeak onto a few lists at the end with Wolverine and X-Men Apocalypse.

So there you have it. When it comes to making terrible superhero movies, DC is considered the worst ... by far.
