I have a few opinions about this topic. Now, mostly for lack of funds, I'm currently what would be so cleverly referred to as a plainskin, so perhaps my opinion does not matter. However, as a visual artist and someone who not only has a keen interest in body art but also has born witness to a number of both excellent and terrible tattoos, I'm going to voice my opinion anyway.
I honestly feel that the increasing popularity of bad art has more to do with the notion that having a tattoo somehow makes you a more interesting person. I find that there is a correlation between underdeveloped personalities and uncreative, overdone tattoos. I know too many girls who've overheard their crush saying that he thinks tattoos are hot and soon after show up with some flowers on their ribcage, or birds on their feet, or a cliche word or phrase across their wrist. Their interest is not in the tattoo itself, but in the response that having the tattoo will elicit. Of course, that mentality is not exclusive to the ladies, but you get what I mean.
I don't believe that there is anything outright wrong with script, but I do think that it is very easy for those tattoos to go awry. I have seen far more, in my opinion, bad text tattoos than good ones. That being said, I plan to work a quote from my favorite story into my first tattoo. I also plan for the script to stand beautifully as a whole, without having to know what it says. Is that uncreative? Maybe it is, but I'm also getting it to please myself, not to be creative.
It is my personal belief that a bad tattoo can often be traced back to the person getting it doing so to please other people. Still, I don't think that genuinely loving your tattoo makes it good either. Nothing makes me more angry than when people say that you can't judge a painting because anything is art. There are measurable elements and principles that must be in play in order to define something as being a work of art. Generally speaking, whether the artist is conscious of them or not, the more these elements and principles are being used, the more pleasing the work is to the eye, and if they aren't present at all, then it is not a work of art. The same goes for tattoos.
