Uninspiring and certainly Unoriginal.
I don't think I've ever watched a film that had so many direct quotes, dialogue and scenarios from previous prequel movies of the same franchise.
Despite the great sets it was hard to watch and unlike the prequel originals which were fresh storylines with realistic and believable characters, this cookie cutter was done with the "it worked before so just do that again attitude".
I'm surprised with the more positive reviews and can only suppose that they were from people who never saw any of the previous Alien movies.
