What sort of crap writing is this

The fire blazed weakly on the hearth.

I am nearly finished the slightly wine stained book, see earlier post, and I came across this sentence. Maybe my understanding of the words is wrong, but I would have thought a fire is weak or it blazes, but not both at the same time.

Totally broke my concentration, just like a badly placed ad on tv, and aren't they nearly all badly placed.

Well, time to turn off the dim bright lights and go to bed.
