i want to vanish-elvis costello

you go to see a movie. and it's not that good. it drags, and the plot is cliched, poorly written, characters enter and leave without explanation. it's bad. but not so bad that you'll walk out on it. you paid good money and maybe the ending will have some kind of reward if you ride it out. so you sit there.
but when it's over it feels so good to stretch your legs.
