Have you seen Shrek the third? Dont bother?

I live in the UK an this movie was just released here. If you havent already seen it then dont as it will taint your impression of the fantastic shrek 1 & 2. It is total and utter rubbish - cameron bloody diaz and justin redneck timberlake telling "hollywood jokes" that only LA bloody lactor ovies would find funny - utter sh1te - like watching an american sitcom that thinks its hilarious but is really moronic - made me sick
