I remember liking Suicide Squad better than most people did, even if mostly by comparison to other DC movies on offer in the same continuity. And my just glanced-over review bears that memory out.
The Suicide Squad is kind of an oddly named sequel? It’s maybe slightly closer to reboot than sequel even though there is character continuity and it’s clearly still part of the DC Cinematic Universe. Basically, it feels like James Gunn came along while he was briefly persona non grata with Disney and said hey, DC, you know what would make this movie better? Leaning into the comedy part and out of the grimdark part. And they listened!
There are a few things he did especially right. First: it is over the top. The plot is over the top, the violence is over the top, the character are all aware of these facts and embrace their ridiculous, hyper-violent, insane world for what it is. Second: it is funny. This is another thing the characters embrace. I don’t know how to explain exactly what I mean. It’s not like they’re trying to outfunny each other. But there’s an absurdity to everything that’s going on, and they lean into it instead of staying aloof from it. Third: would be a giant spoiler to actually say, but trust me. Gunn understands the world in which he is operating, and I do not mean DC at large, I mean this series in particular, of which I hope to see more.
This is the new best DC movie, and their trendline has been so solid that I legitimately want to see whatever they make next. …I mean, as long as it’s not another Superman.
 For historical purposes: he got “canceled” by right wing people who were tired of seeing their heroes be “canceled” for things they were doing in real time, so they dug up things Gunn had done years earlier, and Disney briefly listened to this and took it as the same kind of thing, instead of noticing that he had learned from the past and was no longer doing those sorts of things. Later, they got over it and there will be a third Guardians of the Galaxy movie after all. Still, I cannot hate the outcome of his personal digression.
 For additional historical purposes: canceled is when you did something wrong, and people called you out on it, and consequences ensued. Prior to a few years ago, the people calling you out part rarely happened, and consequences ensuing happened so rarely as to be basically never.
 Well, except for Amanda Waller as the orchestrator of the squad and its varied missions, who takes everything and herself just as seriously as she did last time. But even this is an important aspect of the story being told.
