But it's not that. Really. I think Terry Eagleton, the well-known Marxist literary theorist, offers a position that explains why criticism of seemingly inane cultural phenomena can be useful:
Marxist criticism is part of a larger body of theoretical analysis which aims to understand ideologies - the ideas, values and feelings by which men [sic] experience their societies at various times. And certain of those ideas, values and feelings are available to us only in literature. To understand ideologies is to understand both the past and the present more deeply; and such understanding contributes to our liberation (Marxism and Literary Criticism 1976, p.viii).Substitute 'literature' for film, TV, music, etc. and you've got a powerful justification for teasing out the ideologies curled up tightly in the likes of Mamma Mia, The Sopranos and Eric Prydz videos. And what's more, you have a critical practice that is very well suited to the blogging format.
That is why I occasionally write about tat.
