I think the "Alien" tag is really doing this movie a disfavor. It has not to compare to the first Alien, cause it's simply not a direct sequel. The second iteration of the series is a rather simple action movie and wouldn't stand the comparison to the space opera, that is the first one. Still it's a great movie and loved by fans. Today you don't really get that chance by fans anymore.
I think the A.I. thematic is great, Michael Fassbender is superb as always, the atmosphere is thick as fog and the audal and visual design is really unique.
Yes there are plot and logic holes, admittely very present ones. Yes the second half is weaker than the first, which is always disappointing. Yes people are acting dumb in this movie. (like in every alien movie)
Still - Most underrated movie of the last years. (regarding alien fanboys' rating; not letterboxd)
