No, it really isn't.
It's respectful to Alien and Predator,
as much as a PG13 Paul W.S Anderson is able-
but it's rendition of the titular beast visually, thematically and narratively (lifecycle, ability, durability) is completely warped.
As far as "real" representations of the Alien goes,
I count Alien, Aliens, AlienĀ³,
Isolation, Covenant and The Cold Forge.
And a number of the DH stories.
