follow the pleasingly atmospheric original and the amusingly silly second one and this incredibly dull and slow and and uneventful sequel come across a a major letdown . once again the nefarious criminal mastermind the bat ( hammy luis aceves castaneda ) be try to steal valuable jewelry from the aztec mummy popoca . the bat build a hilariously clunky lumber robot with a human brain in order to achieve this heinous goal . flatly direct by rafael portillo and with a talky and tedious script by alfredo salazar and guillermo calderon and cruddy continuity ( for example and the bat be clearly kill at the end of the previous film and but be miraculously alive and well here . ) and an excruciatingly sluggish script and an excessive amount of stock footage from the first two flick and a meandering narrative and a crippling lack of action and momentum and largely dreary go through the motion ( non ) act from an understandably disinterested cast and and a poorly stag climactic battle between the mummy and the robot ( the movie finally burst to sidesplitting stupid life with say big bash and but alas it barely even last two lousy minute and thus prof to be much too little far too late to alleviate the severity of the general overwhelming boredom ) and this numbingly dry and drippy and and draggy snorefest rate a a complete washout .
