And recently, Railgun's third season (first two are subpar, but that's more the source material's fault)
well ... I loved the first two XD, and this third was another level.
We need a 4th and with that level of production that was spectacular
I have re-watched some animes, but not because I like them as such.
The only animes that I have re-watched for my own pleasure were
ReZero [when they broadcast the first season again] and mainly because I wanted to remember things well to see the second and I took advantage of the occasion. And
Oregairu when they released the 3rd season [I just love oregairu there was no more reason]
I do not like repeating animes and I have a very good memory so I rarely need to do it, to not remember things it has to be that I did not like it very much and if so it is one more reason not to do it XD
aaah I just remembered that I also re-watched
Toradora when I read the light novels [very good novels compared to anime XD]
