First things first, the movie was good and anyone who likes the Suicide Squad comics or animated films won't be disappointed. Simply put Gunn delivered. Also if you like the HBO Max Doom Patrol show, its pretty similar to that too.
The interesting thing for me is that it felt like he was able to bring out his full directorial and writing style with this film. If I were to compare all his cbm I like this one the most and its because I think his personal style and tastes melded better with the characters and their stories but others may feel differently.
The cast was great in their roles, I can't think of a single person who I didn't like.
The writing was very good. You can tell that Gunn likes these characters and comics because he didn't let a single character get too much screen time imo. Because he gave everyone a decent amount of screen time the movie never felt overcrowded and whenever your favorite character showed up it became a highlight. Some of my favorite scenes were Amanda Waller and her team, he depicted them very well and they were hilarious.
All in all good rewatch able film. Is it the best dc film I've seen? No but its a solid film and I look forward to seeing him make more movies.
