BVS, to me, was like an essay given a month in advance and you hold off doing it until the weekend before it's due. Some decent ideas floating around, but just a lot of sloppy execution (look no further than the JL cameos) that muddies the whole thing up. And it's funny that what I've described sounds like a rush job, when the thing ended up being f***ing delayed for almost a year.
Suicide Squad I enjoyed quite a bit and thought a lot of the harsher critics were being really hyperbolic, but the conflict at the center of the film was really weak and too standard CBM for something that could've been a real departure for the medium. Editing deserves some blame for the final product, but they didn't edit in an entire conflict.
As for X-Men Apocalypse... I don't know what the hell happened there. I just can't make sense of it. They were coming off arguably the strongest film of the franchise, they opened up a wide canvas for themselves continuity-wise and... they did
that. They blew it with Oscar Isaac, Fassbender's presence was unnecessary (with the exception of one sad scene), and with the exception of Jean, none of the newbies really got anything memorable to do. The whole thing was just alot of spectacle without very much fun to go along with it. And the visuals also weren't very good either, so.
And, while I'm all for calling an overrated MCU spade a spade, I really enjoyed Civil War. While not wanting to turn this into a DC vs. Marvel thing, the conflict between the two main heroes
actually worked, if perhaps being a bit one-sided. They nailed the introductions for the soon-to-be going solo heroes and it was just damn enjoyable. I'm sure there were flaws that plenty of critics and fanboys alike didn't fail to sweep under the rug, but compared to some of the other CBMs this year, those flaws were negligible.
Lastly, I can't say anything about Deadpool that hasn't already been said.
