Not quite as bad as those from the 1950/60's, but surprisingly poor CGI for 2016: The monsters are visually obvious additions. At one point, a dog-like creature attacks a man who - instead of trying to use his hands, throws them up! The acting was OK, as was the dialogue. The plot had reasonable promise but only for about a half-hour. The interactions between good and bad guys was believable for the most part. I don't think any interaction between the monsters and anything else - buildings, humans or other monsters - was believable. Shocking when almost all films rely heavily on such nowadays. Perhaps Sc-Fi channel has too rigid production schedules, or lousy quality control?
