Having read many YKYHWTMEW (You Know You Have Watched Too Much Eva When), I have come up with . . .
You Know You HAVEN'T Seen Enough Eva When. . . (or your an idiot about eva when)
... you think that it is "Just another mech...."
... you still believe that the plot is important.
... you hate the TV ending. (Clearly hasn't seen EoE)
... you don't analyse yourself to see if you have any similarity to the characters and their problems.
... you think Gendo is a complete villain.
... you don't think about yourself.
... you're still sane.

... you're still alive.

Feel free to add more.
p.s. please don't flame me, I burn easily.
