For the record I voted "I have seen it and I liked it", despite having given up on Torchwood near the start of the first season for precisely the reasons you give.

I also think that you'd still hate Torchwood: Children of Earth, but for slightly different reasons.

(For me it finally began living up to its theoretical premise as an adult Doctor Who; Children of Earth resembled something like a cross between Quatermass and Spooks.)
