14 years old now, it seems.
This show came out around the time I entered university. (I only got into university when I was 21. Not 18 like the majority do). I remember watching the first couple of episodes and not vibing with it. So I gave up on the show rather early and had university and other stuff to focus on instead. I missed its entire run.
I thought I felt old when the 2k3 cartoon was no longer the "new TMNT cartoon", but 2012 no longer being the newest TMNT cartoon hits harder
