Plot holes this plot holes that....
Do people just got this word and its fancy now use every single chapter???
Plot hole is a gap on the FLOW of the history or the logic set.
There are several problems, like Continuity, that should not be mistaken by Plot hole
Examples of plot holes would be: Sandaime tell that the Kyubi was sealed 20 years ago, while naruto is only 15 making it impossible.. see..
But a Continuity problem would be, we see a shot of Konoha montain with all Hokage's and its FULL as in there is no more space, but after some time, somehow the montain "grew" enough for Tsunade's face fit..
Thats not a plot hole but a continuity problem
THOSES WERE EXAMPLES before someone go screaming
