Unforgiving slide film

After using digital cameras for years and shooting negatives when I want film I think I may have forgotten how unforgiving slide film can be.  I shot a roll of Elitechrome through my Fujica 35 SE and was very disappointed with the results.  I under exposed nearly everything, either through misjudging the light or because the shutter speeds where off.  Ordinarily with negatives I would still have usable images but most of these transparencies, well they aren’t very transparent.  My only recourse seems to be to process them as high contrast B&W images.  There just isn’t any room with slides to get the exposure wrong, I have one more roll in my stock but if I buy more I will be more cautious about which camera I use so that I can rely on the exposure being correct.
