How is this film anything near to 'good'!?!

I saw this movie a couple of days ago and I was absolutely stunned. This is the stupidest film I have ever seen and trust me, I've seen plenty.
1. The murdering sheeps look like they've eaten a truck of uncle ben's ketchup.
2. I haven't heard ONE SINGLE song during the whole production and it should be an action film with tense scenes.
3. The acting is simply horrible although it is funny in it's pure stupidity.

The cherry on the top of the cake was the ending. The farting sheeps and the way he threw the lighter, not to mention that the whole building exploded but they didn't have a scrach on them after the bang is just retarded.

I could find alot more reasons why this film is absolutely horrible but ... it's just.. you've gotta see in and try not to laugh at the stupid parts, you will then notice that it's just plain stupid.

ps. oh yeah. I've learned that if you get bit by a diseased sheep you metamorphosize into a sheep-o-sapiens looking thingy that moves it's lower jaw uncontrolably.
