For the record, I am not saying good movies can't be fun. I am saying that if in the end "fun" is the best thing you can say about the movie, then you have failed at defending it. I find Batman and Robin to be a fun movie. The acting sucks, the story sucks, everything about it is terrible. But, it's so bad it's good, so it's a fun movie to watch. Would that convince you to watch it? No, and it shouldn't.
Again, not saying that a good movie can't be fun, I have seen a lot of comments about certain comic book movies not being "fun" and just being dark and joyless. That is why people are such fan's of the MCU movies, because they are "funner" than say Man of Steel. But if the premise isn't fun, why make it so? If an alien army invades Earth, I highly doubt it would be a fun ride. And I think the people fighting those aliens wouldn't be having fun either.

I think many people confuse the words "dark, gritty, and joyless", "realistic", and "dramatic". If you want a "dark, gritty, and joyless" comic book movie, look at Sin City; if you want a "realistic" comic book movie, watch The Dark Knight Trilogy; and if you want a "dramatic" comic book movie, watch Man of Steel. There are huge differences in all of these movies, yet a lot of people tend to clump them all together to make "dark and grit". Look, if you don't like the movie, fine, but call it out for what it actually is.
Now, keeping in mind that these are different movies, are any of them "fun"? Yes, Sin City's stylized violence was a really cool thing to watch, making it fun; The Dark Knight trilogy, while realistic, was packed with fun fight scenes, and the epic score made it better; Man of Steel's first flight sequence, mixed with the score and effects, was a really fun thing in the theater, I couldn't stop smiling! Now, each of these movies bring something positive to the table, fun just being one of them. You can not fully describe any of these movies by just using the word "fun".
Now, what is just "a fun time at the movies?" Well, Iron Man 3. Now, I wasn't a fan of this movie. I think that besides the Mandarin twist, there was so much lacking in this movie. The effects weren't as good as the previous, it was basically just RDJ being RDJ, it put off all character development first established by 3 movies for Iron Man..."OH BUT IT WAS SO FUN! THERE WAS SO MUCH COLOR, EVERYTHING WAS COOL!
FUN TIME AT THE MOVIES!" Do you see what I mean? If I can list off 4 huge negatives, but say it's fun, does that mean I complimented it?
Look, as I keep trying to say, good movies can be fun, they don't have to be serious all the time. But if all I can say is that "it's fun" it's immasculating the movie I think. I mean, if I want just some random fun, I'll go to a park, go down a slide, and say "WEEEEEEEEEEEEE!". But if I want to see a movie, why am I going to pay $10 to watch something that you can only describe as fun?
