Basically no. I never feel like rudiments are boring. There's so much going on even when playing 'simple' rudiments like singles - all the time. Of course it depends of how acute you are - hearing, vision, general disposition to motions/physical awareness, rhythmic awareness, dynamics... good posture. So many parameters! So no matter what I'm playing, my ears (or other senses) would tell me that I could do better most of the time, and often times also where the issues lie.
I can imagine tutorials like Stick Control can get boring but it's not the book, it's the user!
Mindless practice isn't effective, but focused practice is. Now assuming that you're practicing focused - how can that be boring? Maybe your ears aren't developed enough to catch all those subtleties (dynamics, timing, stick height, symmetry of hands/grip - if matched). Maybe your hands aren't sensitive enough (yet) to feel how they should micro-readjust your grip etc. This is normal and will keep improving for months if not years.
Don't try to digest too many exercises off Stick Control. Focus on a few, analyze the motions, work on them. Build from there and slowly add more motions/rudiments. Really, I could play a single stroke roll for longer periods of time and it wouldn't get boring. Maybe you should learn just a handful of rudiments, get them down well and then have fun stringing them together for endless patterns. Shift them through various subdivisions - if the exercise is in 16th notes, make it triplets! Or vice versa. I would always switch gears when practicing rudiments. Also learn everything with your L hand leading - how is that boring? ;-)
One thing that has made my practice much more fun is the Ludwig P4 pad (designed by Pat Petrillo). Check that one out, you'll have much more options than regular pads - getting used to play accents 'around the kit'/on various areas and also to various rebound feel.
