I enjoyed Prometheus more. It was sort of new. This thing kind of imitates the earlier Alien movies and adds some stuff, but the alien parts is just not that engaging. They should probably stop making these films now.
I rank this as the 4th best in the saga. Way better than any prequel and I think it avoids every single thing I hate about the prequels. Is it perfect? No, but very good. This is the Star Wars-film I've been waiting 32 years for - and it sets up episode VIII nice.
