It's not so good... The best acting in it was by Arnold and he played a robot! The leads are mis-cast, they have no chemistry, and John Conner looks like an asshole from the jump. They ruin the flick by doing all the same tired San Fran destroying we see every Summer (x-men, rise of the apes, Godzilla ) and have already seen once this summer (San Andreas). ...The great thing about T1 & T2 was the well told and interesting story. Here it's just seems secondary and rushed to get to the next explosion. Oh and there one huuuuuge plot hole but I let u point it out.
Save you're money Watch T3 and you'll end up with the same result... Disappointment.
