      The movie is bursting at the seams, as if Choi, in his first outing since the 2015 historical action drama “Assassination,” was drunk on pure filmmaking pleasure and threw every cinematic genre into a gigantic blender.

      The sheer too-much-ness of Alienoid could have easily been wearying, given its many tangents and supporting characters. Thankfully, writer/director Choi Dong-hoon confirms his hitmaker reputation by balancing over-inflated set pieces with disarming screwball comedy and delightful character actor performances.

      The story is very high concept and the tone is completely aware of itself, leading to a truly enjoyable experience

      It’s all eye candy and spectacle, all a bit much and pointlessly hard to follow. But make no mistake, this is something to see, even if making sense of it can feel more trouble than it’s worth.

      Austin Chronicle

      Alienoid is so big in its ambition that it rarely coheres, and sequences in each time period go on for so long that the other era, and all its characters, fall away. But the characters are overwhelmingly entertaining, most especially Jo and Yum as the hapless monster hunters who are promised much bigger things if Part 2 ever happens.

      Screen Daily

      Hamstrung by lumbering plotting and variable special effects, this first part is an unimaginative hodgepodge which leaves its well-assembled cast stranded across time and space.

      Alienoid is a movie that wants to be everything and satisfy everyone, and when you try to satisfy everyone, you invariably end up satisfying no one.
