Why I love this movie
I saw a few posts about why some people think this movie is not funny, thought I'd post about why I think it IS funny.
I didn't find the movie particularly funny on first viewing, and I can see why it wouldn't suit everyone's sense of humour because it is indeed silly, ridiculous and sometimes non-sensical.
It took me a second viewing a few years later to actually appreciate the humour.
First of all, this movie is satirical in nature, it mocks the concept of sexism, as well as narrow & simple minded people by exaggerating on how stupid it is/they are. As a result, the movie may appear 'stupid' or 'silly', because, well, that's what it is (successfully) depicting! Because of this, I think of this movie as more than just another silly comedy, but one that actually has, more or less, some depth and meaning to it, and I appreciate that aspect of the movie.
Secondly, there are so many great one liners and quote in there, I often find myself can't help but quote Anchorman when it's fitting (one example, 60% of the time it works everytime).
Thirdly, the insults in this movie are great, if I could learn all of it, I would use them all the time! (as a joke of course) They are, as some might call it, ridiculous. Some of the insults are not insulting at all, or are so over the top that it is more funny than offensive, and that's what's great about them, that they are not actually insulting if you can appreciate the 'ridiculous' sense of humour!
Ultimately not everyone will appreciate it, you really need to have a specific kind of sense of humour to like this movie.
P.S. I saw someone posted that they preferred Step Brothers over Anchorman. I mean, really? I didn't like Step Brothers at all. But anyway, don't we all have our preferences.
