Batman Movie! nicee..

Well, as the headline stated, it really is a very nice and great movie i've seen so far..Moreover, it has a very long duration which is 2.5 hours.It's worthed! But nothing is perfect though it has a not-clear ending for me ( or is it because i don't understand?? ) There's something missing at the end of the movie..not completed..But it's weird 'cause i didn't laugh when everbody laughed? For me ' is it funny? or did i miss something supposed to be funny?' overall this is quite nice movie..a bit scary though.. :D
