best alien movies

Do not know if this is the right place to ask, but here goes, what I am looking for are good alien movies featuring greys, area 51, abductions, etc but made in the way as how we ufo truthseekers see them, not films like independance day where they go to area 51 and spoil it by showing a star wars type alien craft, instead of the normal saucer type or the lazar sport type.
I am sick of movies showing aliens in other forms than the alien greys that we all percieve them as looking.
Visitors of the night, wow great aliens in that movie, more of this type I want, but cannot find. Can anyone recommend any to me.
Anyone wonder why no one has made a blockbuster based on an area 51 infiltration, would be great?.
Found a good list of alien and conspiracy movies here,

www.cduniverse.com...

But the good ones here I have seen.
Liked mission to mars, that type of stuff, based on real theories,
please can you help, think best people to ask are on here because you know the story.
Thanks.
