First of all, the original Shrek film does not bother me that much, my feelings towards it are neither like or dislike, just "meh!". The story of Shrek is not terrible, it just seems very thin, every plot point you can see coming a mile off, and the story seemed to be fleshed out purely by Eddie Murphy being annoying and not keeping his yap shut and the humour is...well In my opinion not humour, there's only so many times a CGI ogre can belch before my attention wanes. Yes I do think that Shrek got way too much attention, it is hideously overrated, but I was willing to let it be.
My real beef with the franchise comes with the dawn of Shrek 2, a film with so little imagination or story, basically the first film with the scenes edited in a different order. People whine about the Direct to Video sequels Disney release, saying they lack imagination because they either, reverse the events of the first film, or go back and unpick something that didn't need unpicking, and then go on to praise Shrek 2 when it is guilty of the same crimes. Shrek 2 survives solely on the hope that people have seen the first film and relies on pathetic jokes that we have all seen a million times before, I mean ''Are we there yet?" jokes weren't funny years ago, and they're still not now. Yet for some reason about a minute of screen time is taken up with them. Dreamworks idea during the production of Shrek 2 seems to have been "If you can't come up with an interesting plot development, throw in a cheesy joke, make the ogre fart then make a pop culture reference and it just forms a final product which is empty and weak.
Also the animation is just so sub par, to anything other studios produce, the humans espescially have crap designs, the move awkwardly and they all look the same. I mean take this image from the upcoming Shrek 3

I mean just look at them! Take away the hair styles and all the bloody princesses look the same!
And my Shrek 2 rattles my cage even more is that this cinematic diarrhoea was gobbled up by slack jawed morons across the world making it the highest grossing animated film of all time!
Insanity, pure insanity!
For anyone who likes the Shrek films, you're welcome to them and I just hope the local nut house comes to cart you off ASAP!
