Personally (my PhD is in experimental physics) the interesting bit is all the vacuum pumps, magnet control, beam dumps, control systems as well as the detectors.
Whether some semi-imaginary particle fits the parameters of some semi-imaginary theory is pretty uninteresting ;-)
I found that once you get past the technicalities and when you get back to a bird's eye view, interactions among elementary particles follow almost naturally and looks deceptively simple [0], and the postulate of the Higgs boson existence seems like one† of the obvious solutions explaining mass.
Now when you get back down in the trenches and have to properly define it theoretically I'm positively convinced it is another matter entirely in terms of complexity.
† Then again, we previously tried to explain how light could be propagating through a postulated medium called luminiferous aether. Hopefully it looks like the LHC experiments are not going the way aether experiments did.
