Ok let's go through this V:

Dr. Loomis is not the leading character, that would be Laurie, so yes

Captain Spaulding, is definitely a side character, so yes

Columbus is the lead in Zombieland and I'll concede that Tallahassee is the co-lead.

Dr. John Markoway, okay I'll concede on this one.

Granny Boone, how you could consider her a lead role is beyond me, I still say yes.

Luke from the Innkeepers, Claire is obviously the lead and Luke barely does anything, so yes.

The Stranger, he is in no way the main antagonist, so he is a yes

Disagree with me if you like but I feel confident that I am right on these. I will only accept a character as a co-lead if said character has just as much air time as the main lead like in Men in Black, Will Smith is the main lead and Tommy Lee Jones is the co-lead.
