Word of mouth isn't toxic. A lot of fans love it, some like it and some are Ok with it or confused. Most of the negativity come from trolls that haven't seen the movie.
I like the sad video because it has a song that was used in Watchmen in the Comedian funeral scene who happened to be the same actor that played Thomas Wayne in this movie.
I thought the talk about Man of Steel leading up to this movie was bad but boy the internet from this point till Justice League is going to be a sight to behold.
