i used to just think episode 5 was ok, but after seeing that movie, i decided that:

episode 1: pretty good (qui gon jinn is my favorite character)

episode 2: ok (the acting was bad, but it was funny bad, plus there were cool action scenes)

episode 3: OMG TEH FRICKIN AWESOMEEST MOVIE EVAR!!1! (no need for explanation)

episode 4: pretty good. (im to lazy to write something for this)

episode 5: TOTALLY SUCKED ASS!! (this movie was soooo boring, the biggest snorefest ive ever seen.)

episode 6: pretty damn awesome (i dunno, its my second favorite now.)
