I have to say that I am at a loss to see why everyone is getting so defensive about this.
As
Essex has pointed out, to
bash something, in the sense that we are discussing, means to criticise it heavily. So, if you repeatedly criticise the films, or any aspect of them, you are bashing them.
Nothing wrong in that per se. The important point is that you back up your arguments with reasoned analysis. I don't believe that I have ever
bashed anyone here for not doing that.
