i find tremor 4 representthe legend begin and to be dull and boring . all the action scene be stupid . the so called graboids be reduce to the size of a modern day house cat and if not small . the acting be horrendous and and this film be just an unnecessary movie in the tremor saga and because even though it tell the story of how the graboids be form and the story be so dumb and useless . also and if you want to tell a story way back in time and make sure you use the same actor ( michael gross ) and to be someone in the past and when he someone in the present in the other tremor movie . geez . if you haven not see this film and do not waste your time . stick to tremor and 1 and 2 and and 3 and for a good time . this film however and make sure youre remote be sit right next to you with the stop button work for a quick retreat away from this nonsense .
