Not that it matters much but I wish I knew how old your are ... some of the way you phrase things points to you not being here for the OT in its "glory days" from 77 - 83. I'm not saying this in a bad way but it is VERY obvious that your knowledge of SW is limited.
As has been said, Sci-Fi movies very rarely get a best picture nomination. Sci-Fi movies get the nomination in visual effects, music ... etc. but rarely best picture.
Who declared it "better than the original"? the fans ... since when does Hollywood listen to the "fans". Yes, many fans think that ep V was the best of the OT ... myself I personally liked ep VI the best of the OT ... it comes down to, as it always does with SW, "a certain point of view".
The truth is that Ep V was the lowest grossing of the 6 Star Wars movies ... yet fans say it was the best of them ... if you can figure that out then you're ahead of me on that. I can offer a couple of my thoughts on it ... first, the movie was the "darkest" of the OT which usually happens in the middle "act" of any story. Second, many of the "secrets" revealed in the movie were leaked before the movie came out. Third, the 5 words said by Darth Vader to Luke at the end of their duel absolutely STUNNED SW fans ... It turned everything we thought we knew upside down. Other than that it's always been a mystery to me as to why it's the lowest grossing of the 6 films.
Why was it called "The Empire Strikes Back" ... here is where your lack of knowledge about SW really shows. The SW story is a straight line story meaning that it builds on itself. In ep IV the Rebellion took out the Death Star ... kind of a crushing defeat for the Empire. After a crushing defeat what do you want to do ... Strike back with all your might ... that's why it was called that. The Empire got their big new "toy" destroyed in ep VI so it's only natural for the Empire to want to Strike Back. Get it??
SW vs ST are always questions that have no answer other than the opinion of the fans of both series. Personally I like SW better than ST but I'm a ST fan also. In my opinion the only one of the ST movies that comes even remotely close to being as good as any of the SW movies is the most recent one ... box office numbers will back that up big time.
As it stands now Star Wars Ep IV is the 4th highest grossing film of all time ... all 6 of the SW films are in the top 35 of the highest grossing films of all time. It's only proper that the top of the list for highest grossing films of all time includes the names from 4 guys who were in film school at the same time and were best of friends ... Lucas, Cameron, Spielberg, Coppola. There's some heavy duty talent right there.
In the end trying to put any kind of "reality" to the Star Wars saga is impossible. It came along at a time when the public was yearning for something new and it gave it to them ... along with changing the movie industry forever.
May The Force Be With You ...
