then you should be good, district 9 is definitely more alien (realistic plot that only requires suspension of disbelief only for existence of aliens, matrue dialog, stronger charater development, good special effects that aren't the main focus and not distracting from story, ect...) than armageddon\independence day (plot requires suspension of disbelief, terrible dialog that relies on one liners, paper thin charaters, film selling point is special effects and big name actors, ect...). they could be different genres really.
