Yes, the second Transformers movie turned out to be remarkably spectacular, with good humor that doesn't turn the film into a comedy, and seemingly everything is fine, but the plot itself isn't very original or captivating.

In my opinion, it's more of a comedy with mind-blowing action, a typical summer blockbuster to watch with your brain turned off. And for some reason, many people didn't appreciate the humor, although you just need to approach such films with a more relaxed attitude.
As for District 9, everything has already been written above.
