>>83415724Doomsday was admittedly one of the more entertaining parts of the movie, but it didn't make sense that Lex would create an Alien Laser Hulk when he already hates aliens. There's no scene showing that Lex's plan went awry and Supes had to fix it, which I think was the idea.
Of course in the end it turns out that Lex is not, as we thought the whole movie, working to stop the threat of alien invasion but instead seemingly either corrupted or actively working for Darkseid, which is something only a comic or cartoon fan would know from the inverted painting, Knightmare sequence, and ringing bells.
If the average schlub on the street watches that movie, the obfuscated greater plot (that's the actual plot of the movie) would not be clear, and even with the clarity delivered by being a fan it's not enough to make Doomsday anything more than a big flashy CGI sequence to finish the movie, which ironically is one of the big problems with the MCU, only instead of it being the heroes fighting 50 million little assholes with shit flying all over the screen BvS does just one guy, so it's all the same. Of course there really wasn't much else of a way to do it when it's a team up or crossover.
Furthermore, Superman's death is so cheap, obviously fake, and comes far, far too soon. Death of Superman was supposed to be about a beloved old character and symbol of hope and compassion getting fucking murdered by some random living weapon, and then cynically returned to life. BvS is about a really conflicted and young symbol of uncertainty and strength getting murdered by some guy who doesn't like him and is also somehow corrupted by the Space Devil using a zombie, and then being cynically brought back to life. Why should I even care that Superman is dead? Why waste time filming two funeral scenes for a guy I don't really like yet, and also isn't dead?
So basically Doomsday made for a cool sequence, but besides that he actually kind of shits all over what plot there is.
