Funny, but I never understood why people label Hal as bland.
Hal was the one who usually enjoyed having a little fun every once in a while, compared to Bruce whose millionaire playboy persona was only something he kept up for public consumption and Barry who was a bit of a science nerd.
Is it because he doesn't make lame quips while he's fighting some bad guy or break the fourth wall to make a stupidly quick pun?
Hal's a moderately conservative Irish Catholic with a sense for excitement and adventure, but also a sense of honor and duty (being a U.S.A.F/turned private test pilot and a member of an intergalactic peace keeping force)
It just depends on who is writing him (like every other character)
