The Deeper meaning to it all.

[The Only Real Estel]

Well, me thinks that Gimli was just there so that men would take one look at him and either go out and buy a fancy new razor, or stop shaving all together

I think that Rob Zoombie gave Peter Jackson some pressure to encourage people to go for increasingly wacky hairstyles, personally.

And it's pretty obvious that the stark contrast in the films between light & dark was only to encourage people to buy lightbulbs with more voltage--or else they'd turn into a giant, all-seeing (most of the time ) eye. It's also interesting to note that the big battery companies jumped on the same bandwagon & used the you'll-turn-into-a-huge-eye excuse to promote their battery rechargers.
