I'm not sure if this constitutes as an Alien movie, but Solaris stands out as an intense and haunting bit of science fiction. There is no overt physical extraterrestrial contact, but the hallucinations experienced by the human explorers implies the presence of an unidentifiable alien force. The same can be said of 2001: A Space Odyssey, perhaps the greatest science fiction film ever made.
That's a bit difficult for me as I've seen so many alien movies in my time that were good in their unique way, so its hard for me to answer that. However, I can tell you the best alien film this year was definitely "district 9" that film literally questioned the nature of humanity, and it made the aliens seem more human than us. Which makes it sadder because as I watch that film, I can't help but realize how true that is about us.
Good of you to bring up this very true fact about the movie industry. Some of the old stuff really earns the genius tag for costume, ridiculous special effects, and script. I recall clips of one old monster movie featuring a wooly ape-looking creature wearing a big clumsy Diver Dan helmet on its head. I laughed so hard I thought my stomach would split.
