Feuds That Were Too Short

We all bitch about when feuds go on too long.  However, were there ever any feuds that you thought were too short?  I was surprised the Seth Rollins vs Braun Strowman program for the WWE Universal Title only lasted 1 PPV.  Then again given the fact that the brands would split yet again with Rollins staying on Raw while Strowman went to Smackdown, they had to hurry to get to 1 match between the 2.  

I don't know why they bothered.  That was barely even a feud, it was just something to fill time for one PPV.  Given all the rehashed 4 month feuds these days I'm glad when something is too short.  It's a nice change of pace.
