What was really that bad about X3?
oh gee, I don't know...
The Phoenix being a "split personality"
Rogue giving up her powers
Cyclops dying after 2 seconds of screen time
Psylocke.
Juggernaut.
Multiple Man robbing 8 banks at one time? So stupid and corny I could die
The final battle: X-Men B-squad vs 9,000 nameless mutants
No Nightcrawler
Leech not looking like a leech
the corny dialogue through out
Wolverine being the only one that could save the day....again
"I'm the Juggernaut ******!"
Rogue going from a main character to a useless mutant in background
Angel being a "new character" as opposed to a former student/X-Man
Callisto having Caliban's power
Callisto being incredibly beautiful
Bret Ratner
and many, many, more things
