The fight is meaningless because they team up before the end of the film. Either the movie is going to feel like it didn't do enough justice to the versus portion of the film to get to the finale, or the versus stuff is going to feel well done (our characters will go through their character arcs and learn to be buddies) and have a bolted on finale where they team up to fight the bad guy of the week.I think I've lost your point. Or, at least, this point doesn't match your initial complaint. You said the fight is "meaningless" because you know they team up. But we always knew they teamed up. So, you just don't like how they're teaming up. Basically, you don't like Doomsday, I guess.
I can't see in any way how having them team up to fight a big monster at the end is beneficial to the film.
