The showboating from Janick is a major grievance for some hardcore Maiden fans, doesn’t bother me because he only does on songs where, like Justin says, he’s not really needed for the song i.e Run to the Hills, Iron Maiden (where he uses a wireless guitar pack so he can throw it around), Wrathchild etc. His playing on other songs is practically faultless while still doing a bit of showboating.
I’d still rather watch him play than fretwankers like Vai, Satch, Malmsteen, EVH etc
