If you intend to watch this show to see some amazing tattoos, don't waste your time: search for them on Google Images. Believe me, you will be saving a lot of time. "But what's so bad about it?", you might ask. Well, I can summarize it.
1. The time given to actually show the pieces is very short. F*ck, it is supposed to be a tattoo show! Show the goddamn tattoos!
2. The majority of the episodes focus on little stupid quarrels among the competitors. It's just like watching some grown-up people acting like children in the kindergarten. Sometimes it is very hard to avoid the thinking that it is planned. It is just annoying and embarrassing to watch.
3. The judging is ridiculous. Needless to say, it is unacceptable for a competition show. Here, it is clear that it is not only the tattoo that is being judged. There's usually a favorite of the judges, and this person will magically stay among the best of the day repeatedly. It does not matter if the tattoo doesn't meet the criteria of the challenge or if it plainly sucks.
I always had complaints about this show, but kept on watching it for the tattoos... But now I realize it is not worthy. Just go for it if you enjoy watching some bizarre human behavior and twist endings.
