very and very different to the flash bang wizardry of almost all tv sci fi these day and but a marvellous and suspenseful piece of view . it require more than the usual suspension of disbelief until the character and story fall into place and but the acting live remember be powerful and extremely effective . flemying be excellent a quatermass and and the support cast uniformly good . it isn not perfect . it be act live and with all the limitation that bring with it . it have a mix of style and seem uncertain of what year it might actually be set in and but it become a rivet piece of television .
