I know it doesn't sound good. Jonathon Rigby stated on the b.h.forum that they are vary subtle, so i will reserve judgement till i have actually seen it, but i dont like the sound of it at all. The decent thing to do would be to include the untouched original version also.
'TDRO' is probably my favourite hammer (along side 'quatermass and the pit') and the effects are not great tbh, but it's all part of the charm, and there are ropey effects in a lot of the hammer films so....
