this movie start off ok. the book it be base on be a classic and the design work be interesting and the special effect be pedestrian by today standard but perfectly adequate . then they start change thing in nonsensical way . extra plot and sub plot be add and verne original novel emphasise exploration be set aside in a convoluted story that involve revenge and father or son conflict and bionic limb and and an attempt to make all the fault line on the planet go off at once . i stick through with it to the end and but i wish i hadn not . avoid this one .
