In the words of the creator of this misadventure:
Lord of the Rings is more or less the foundation of modern D&D. The latter rose from the former, although the two are now so estranged that to reunite them would be an act of savage madness. Imagine a gaggle of modern hack-n-slash roleplayers who had somehow never been exposed to the original Tolkien mythos, and then imagine taking those players and trying to introduce them to Tolkien via a D&D campaign.
That sums up the comic nicely, and explains why I kept having flasbacks to the various times when I tried to get my hack-n-slash friends interested in my latest campaign, based on {insert seriously good scifi/fantasy novel, film or comic name here}.
