ROTJ gets a hard time because of the change in tone. It really isn't that bad. Keep in mind: it's not a prequel despite what George would like you to think! TPM works as a film on its own. In the SW universe, it does leave much to be desired. (Damn midiclhorians!) However it isn't terrible. (Except for the damn midichlorians!) AOTC is absolutely unforgivable. ROTS is tedium save for Ewan McGregor channeling Sir Alec Guinness.

Oh, and Han before ROTJ. Especially Han in IV and before-traveling the space lanes far and wide with loyal Wookie in tow-blasting Rodians from under the table at a moments notice.
This is not to mention old Obi-Wan on some fool's idea of an idealistic crusade...
