Not as bad as the many super negative reviews would have you believe

Rating: 7/10 (25 May 2017)

I'm a big fan of the Alien franchise and have watched all the extras of the first four films and can repeat lines from the movies, particularly Aliens, etc. etc. I found Prometheus sorely disappointing in all possible ways...and after reading the many caustic reviews here on IMDb, I was about to write off A:C as well...but then I started to read the many 8~9 star reviews and changed my mindset <---which is key.
A:C is, at heart, a horror film only loosely connected to the Alien franchise. It's a great piece of entertainment with terrific visuals and excellent special effects with plenty of action, a nasty, nasty villain and sufficient slimy henchmen.
That said, if you're an Alien purest and demand logic and reason within the Alien Universe, this movie will be a HUGE disappointment. My goodness...what HUGE plot holes, physically impossible goings-on, key missing scenes (note Fox's mea culpa by releasing some prologue materials on Alien Day (4-26)) and far, far too much irrational behavior. The screen writers should be sent to LV-426.
To enjoy this movie (to the extent it can be enjoyed) you must check your Alien-centric brain at the ticket kiosk. This is a horror film with a requisite amount of gore and action. Go with that attitude and sit back. Over-analysis will just make you angry.
