I just watched it. It was enjoyable, the first half of the movie just took itself way too seriously, it was boring man I saw people pull out their phones my girlfriend included, infact I heard a kid yell out "the first half was so boring" as I walked out, no kidding. So many needless scenes that just made it feel disjointed. The last arc definitely salvaged the movie for me and you can also see the very obvious build up for Justice League movie happening. Batffleck, Wonder Woman and Lex were all great to watch for me. But you definitely see where the critics are coming from with this, so much exposition and creating a forced sense of grandeur. Anyway go watch it, you're bound to at least enjoy and appreciate the experience. It's an OK movie, dare I say good, it just isn't a great movie. The future movies in the DC expanded universe are definitely salvageable and can be built upon, just need to take away Snyder from the helm.
