The originals were great because they were unique at the time being space movies, they had aliens looking like aliens (unlike Classic Trek's Klingons, etc) and they emulated things from car chases, sword fights, western movies, Japanese movies, gun fights and Laurel & Hardy movies, but in a sci-fi tone.
The newer ones are handicapped because too much emphasis is placed on the technical gadgetry and not enough on pure emotion. That and everyone knows how things turn out, so you haver to set up 3 movies with everyonee knowing the final results.
And Greedo should not shoot first! Damnit, it's just wrong, wrong, wrong.
