Everything's Better With Dragons!™
(WARNING: that link goes to TV Tropes.)
Unfortunately, some stories are insufficiently good that even they cannot be ameliorated by the presence of dragons and/or use them in an inappropriate manner such that they might as well have no dragons in the first place because there's just no helping some tales.
Conversely some stories are very good indeed, even though they seem to lack apparent dragons to the untrained eye. You may safely assume that they do indeed contain stealthy invisible dragons
lurking in the margins* and making everything better, much as medieval maps noted that they did†.

serpents of such great magnitude that they can swallow up a cow whole".
