The bad acting and bad directiON is entirely based on your opinion. You haven't given me one solid reason other than that as to why it should go in DC's 'bad list'.
Bad direction = Not picking up on the plot holes that people have mentioned in this thread and other threads countless times.
Bad acting = things like Kate Bosworth as Lois was horrible even more so when you take into account she was meant to playing Margot Kidder's Lois. But that could be based on opinions so I'll leave the acting alone.
However ....
- A plot that was basically movie 1 again
- A subplot with a kid that served no purpose to the film and ultimately lead no where
- Disregarding things that happened before or even the main charracter himself.
- Multiple plot holes e.g Superman moving around perfectly with a chunk of kryptonite stuck him only to lift a mountain of Kyptonite as well at the same time. While all other things in film show him get weak before hand
That's brief as I don't want to go in to the "superman returns good or bad?" talk too long, But that list alone bring the movie down as a movie.
