I'm guessing most of the good reviews are coming from the younger crowd that don't have a very good reference point as to what an actual decent production is. The acting and writing are pretty shoddy. Cinematography and directing is sub par and the chronology is a bit convoluted. A very poor casting choice for J.Allen Hynek.
The only things keeping my casual interest is the subject matter, and Michael Malarkey as Captain Quinn, while although not giving a stellar performance is up and beyond the rest of the cast.
