i understand this movie be make on a very low budget but that be no excuse for the monstrosity that be grendel . deathstalker and the throne of fire and barbarian queen and conquest and the invincible barbarian be all do on shoestring budget and poor special effect yet they still manage to create cult classic by add some scantily clad woman warrior and a good sense of humor . the primitive costume and dark castle and beautiful bulgarian landscape give grendel the potential to be a very good low budget sword and sorcery film and but the maker completely ruin this opportunity by use extremely poor cgi effect and colorless character . compare this film to beowulf ( 1999 ) . it may not be citizen kane but it be a good example of how an entertaining low budget sci fi or adventure movie can be make by use credible special effect and appeal character .
