I went into the movie with no expectations. I really didn't plan to go see it in theaters but my wife was gone to visit her family for a couple of weeks and I decided to go on a whim and see it. I thought it was a great movie but not too great to meet all the hype that was built towards the movie.
I was very pleased to see Michael Fassbender in the movie although he creeped me out a couple of times, and Idris Elba was just spot.freaking.on especially during his last scene in the movie.
I also had absolutely no idea it was a prequel to Aliens and after I had watched the "birthing scene" I even had to go google it while still in the theatre to make sure I comprehended what I had just saw, LoL!
I don't know though, all in all, I thought it was a very good movie. Mos Def one that someone would have to see in theatres, and I already have it pre-ordered through Amazon.
