This is only my opinion, but I think most people here would at least partially agree with it. Indy 4 may not be as bad as the prequels, but it is tonally more similar to them than it is to the IJ trilogy. I would say Indy 1-3 and Star Wars 4-6 have more in common, and Indy 4 and SW 1-3 have more in common, than any other combination of movies from that pool.
I don't feel the need to bash everything GL does at this point. I am still open to good Star Wars. I just don't put up very well with bad Star Wars at this point. That extends to most things really, even Indiana Jones.
