IMDB's Review of Apollo 18
This movies goes pretty much where you'd expect it to go. Kind of an Alien meets Blair Witch. There hasn't been a sci-fi adaptation of that 'found footage' genre, so I guess this is the attempt.
Technical details: The dialog is weak and crew actions questionable. The cinematography is pretty good. Good integration of the old and new, so kudos for that. Acting was hampered by the poor dialog, but was serviceable.
They added some speculation about the Russians I thought was cool and hoped they would explore that further.
If you're a sci-fi fan you'll be disappointed. I am and was.
