Attack of the toxic monster.
9 May 2010 | by (Chyby, Poland) – See all my reviews

Stephen Traxler's "Slithis" somewhat reminded me "Humanoids from the Deep".A gill-man body is made from radioactive mud.This strange monster is butchering dogs and people in Venice,Los Angeles.The police is not helpful in solving the case claiming that the murders are the work of Mansonesque cult."Slithis" is an enjoyable monster movie,but it can be extremely dull is spots.There is not enough Slithis attacks in the movie.There is very little going on in the first hour of "Spawn of the Slithis" and I was bored.However the monster suit is excellent and it should be shown more often.The acting is terrible with vapid performances of an entire cast,but "Spawn of the Slithis" doesn't deserve its current low rating.That's why I am gonna give it 7 out of 10.
