I'll repeat myself that I totally loved the (1987) show as a kid.
The 2003 version, on the other hand, is too far away from the lighthearted feel of the 1987 series, so I didn't like it too much even though the art style is rather similar.
I've also seen some episodes of the 2012 reboot recently, it's kind of nice actually although I would rather enjoy re-runs of the original series.
Also there's an entire
Turtles wiki as anyone would expect but I didn't know of its existence until recently
