Funny enough, these are my top 2 films in the saga, with rots first, and rotj second. However I feel you touched upon a subject that merits it's own discussion in another thread perhaps. The idea that both films are often rated by nature of association to the other two films in their respective trilogies. I think it most applies to ROTS though. You almost always hear of the prequels as a whole in a negative light, not just the first two.
