It was lame in the way the movie (ROTJ) was paced and directed, and the prequels were remarkably lame as movies altogether. They faltered by lessening the whole by association, and making what could have been a good story (at least in backdrop) feel uninspired and mishandled. Sure, Vader was a 'tragic hero' because of the particulars they made his character experience...but we unfortunately had to sit through some horrible films to see it.
Vader's background, his tragedy, and heck...the Jedi altogether...had more impact when we didn't see their history and it was shrouded in mystery. The portrayed fact that he was that whiny, wooden and annoying young Anakin that we saw in laughably bad movies did not enrich him as a character, nor the movies altogether as a series. Again, the concept was interesting, but ultimately worked better left unseen...because the delivery was rather unbearable.
