WOW.
Every time I think I've come to understand just how good this show is, it manages to blow me away all over again.
This should have been the End in more than just name only. These three episodes are a testament to everything that makes this show great. The character work is amazing, the relationships between the team get full focus, robin and slade get the closes thing they'll ever have to closure, and the stakes have literally never been higher.
I do not know how you follow this up. Whatever the S5 has in store, whatever the actual finale is going to be, it has some massive shoes to fill.
Also, I know there is an actual Teen Titans movie...I feel like it can't hit as hard as this.
Though, to be fair, I really should stop ever doubting this show. At this point, it's clear that there is nothing they can't do.
Except make Raven and Beast Boy canon, apparently. Get OUT OF HERE Robin! You have a lady!!!
