The question isn't if the lure looks good to you.  But does it look good to the fish?  Fishing tackle companies have gotten pretty good at making lures look good to fishermen.  If the lure looks good to fishermen, it is an added bonus if the lure catches fish.  I mean what's natural abount a nightcrawler to a fish.  If you recall a previous discussion, nightcrawlers are an invasive species.
