well what be there to say about megalodon and well the cgi be ok the station look like cgi and so dose the water and ice around it the shark look like a shark that be disproportionate his body be big and his mouth be really small . it be really slow moving . there really isn not any story development and the acting be somewhat unbelievable . over all it ok if you be a really big shark fan . i like shark movie and it not a bad movie but it could have be a lot well . i would watch it every once and awhile but it not one to watch all the time it not by any mean a jaw type moviei give it a 4/10 .
