There's no anguish quite like watching a movie that's very clearly saddled with a distinctive anchor around its neck; a single element that just drags the whole thing down into mediocrity or even flat-out awfulness.
And in the case of these 10 movies, we're talking about that one character who pulled off the almost-impressive achievement of single-handedly sabotaging their films.
Sometimes a movie character, whether in horror or otherwise, cuts such a grating, unpleasant presence that they in turn make the entire film an absolute chore to watch, perhaps even encouraging audiences to turn the movie off entirely. These 10 characters range from pointless inclusions nobody asked for, to infuriating changes to the source material, obnoxiously annoying, and even just downright dull.
Each actively worked against anything good the movie was doing elsewhere, enough that all viewers could do was roll their eyes and groan whenever they showed up.
In many cases it's in no way the fault of the actors playing the parts, but simply a script which failed to bring life, interest, and general entertainment value to these boring, irritating, and all-around offputting characters...
10. Rebecca - Renfield
Awkwafina is certainly a talented and funny actress, but recent horror-comedy Renfield absolutely didn't need her surly traffic cop character, Rebecca, at all.
Renfield was a baffling movie of two halves, dividing itself between the thoroughly entertaining toxic workplace satire of Renfield (Nicholas Hoult) and Dracula's (Nicolas Cage) relationship, and a narcotisingly generic crime thriller in which Rebecca takes on mobster Tedward Lobo (Ben Schwartz).
There are far too many moments in the movie where the focus shifts explicitly to Rebecca and her less-than subplot, in turn stealing precious screen time away from Renfield and Dracula.
Nobody compelled to see a film called Renfield had any desire to watch this awkwardly shoehorned cops-and-criminals plot, which feels so out of place as to suggest that the script might be two cast-off screenplays combined into one ill-fitting whole.
Again, Awkwafina isn't the problem here, but her character's existence certainly is, serving as pointless dead weight in a movie which needed to train its attention elsewhere in order to truly succeed. Instead, Renfield turned out to be a fleetingly amusing offering that fell far short of its obvious potential.
