I have played two call of cthulhu campaigns in my life.
The first one went pretty well - the players had fun, and we played it more in the line of movies like "The frighteners," "Cast a deadly spell," and "Army of Darkness" - in other words, horror, but mixed with a heavy amount of dark comedy. It's the only way in my opinion to play it, because unless you enjoy being severely depressed, a long-term campaign in pure Lovecraft style does not work well.
Most everyone played multiple characters over time, because getting killed off is a part of life for COC, and I gave "character points" at the end of each session. People could use those points to add to their new characters to make them more survivable. In the end, since the average character's life expectancy was about 3 sessions, the points did not accumulate too high.
The second game did not go as well, because we played it more seriously, and several players quit as a result. It was just too depressing to play a character, Who started out the best they could be, and would never get better, only worse as their minds and bodies were shattered by the truth of the universe, and crazy cultists who wanted to end everything around them.
IMO, it does indeed work well as one-shots, just as Lovecraft's short stories did, but in a long-running campaign, you need something additional to focus on besides the horror elements, or you get burnt out quickly.
