I've only watched a few minutes so far (not sure I'll go back for more), but I noticed right off the bat that it's filmed in such a way that it looks like a soap opera or a sitcom of yore. I always attributed the difference between the look of a soap and that of a film or primetime drama to the use of videotape over film, but that can't be the case nowadays, surely?
Whatever the reason, The Cape has the same flat, stage-setty feel of one of Spike's favorite shows.
