I don't mind jokes, being a Marvelfag, but I would appreciate the jokes being at least passingly funny.
SS's second biggest problem really was the editing. It felt like half of the second act was cut out, along with Waller's plan and any real scenes of the Skwad bonding enough to justify their dedication in the final act.
The first was Leto. Even cut out as much as he was, his scenes contributed little and the whole subplot with him busting in to save Harley was a complete waste of time.
