Firstly 'Goldfinger' is just a random film in a series based on the 7th book and is not part of linked trilogy. There are worse bond films there are many that are better. ROTJ is better than it.
Secondly 'Quatermass and the Pit' was a remake of a BBC TV serial, not an orginal film but that's no reason to discount it. I've seen some of the Quatermass franchise but not that one, so I'll take your word for it being better than ROTJ.
Thirdly 'Day of the Dead' is inferior to both preceeding parts (Though still excellent). Nowhere close to ROTJ.
Fourthly 'Return of the King' is...... wait... you've got a point there. Damn fine film, first LOTR is better but ROTK is a massive improvement upon TTT. Still prefer ROTJ.
Fifthly 'Toy Story 3', that is a rare example of the 3rd film being the best by far yes. Still pants next to ROTJ.
Sixthly 'Last Crusade' is fun but not a patch on Raiders or Temple Of Doom. But it does actually rival ROTJ for shear entertainment, I'll give you that.
