That it did, for MST, Toby, that it did. God knows that series needed strengthening after the way Tad Williams jumped between main characters so often.
I almost felt like a tennis ball reading that series.
Of course, fantasy can go with absolutely no romance at all, as well. Anything can, really. But I suspect that writers so often contain it in their writing because when it comes down to it, humans are rather dirty-minded creatures, and there's incentive to having intimacy between two people, real or imaginary. Nature made such a thing feel good for a reason.
But that's getting entirely off topic and I shall not say another word lest I get a warning.
But back to weakness in style, and how to deal with it. First off, one MUST have an objective eye scan over their work, either their own (Which tends to be hard to do) or an outside party's. These weaknesses can then be identified. Then, and only then, can one actually hope to deal with it. But how to once you know where those weaknesses are? Well, read it aloud and see how it sounds to you. Does this flow smoothly and easily? Or is it choppy like the Atlantic in a hurricane? Is this or that right? Asking these questions and honestly answering them is the first real step to editing. The hardest part seems to be, though, "What can I replace this section with to make it stronger?"
I've yet to find the answer to THAT question with my own work, which seems to be why I never do any editing......
