Help with a phrase please

[Kriffix]

Hey everyone, long time no question ask. (my ditzy questions were becoming quite frequent!)

Since i'll be in Japan for 5 months soon, theres a certain phrase i'd like to learn since i'm sure i'll be using it alot. Being a big Manga and Anime fan, the phrase i'm looking for is..
"even though i like this anime, i'd rather not watch it since i'm not up to this point yet and don't want to spoil it."
I'm aware that in Japanese a flat out refusal is rare or impolite, and so does anyone know an equivelent phrase that has pretty much the same effect?
I know it's annoying when people don't even try, so i've given it a shot, but i still don't think it's 100% right. (not even 50% )
[Watashi wa] kono anime ga suki da keredo subete no hanashi wo mite inai desu. Dakara mazu subete no hanashi wo mitai desu

Thanks for any help!

（私は）このアニメが好きですが、今私が見ているのはもっと前の話（or エピソード）です。 それからどうなるのか（それから何が起こるのか）まだ知りたくないので、見たくありません。

(Watashi wa) kono anime ga sukidesu ga, ima watashiga miteiru no wa motto mae no hanashi (episo-do) desu. Sorekara dounarunoka (sorekara nani ga okorunoka) mada shiritakunai no de mitakuarimasen.

This one's a toughie. What I would usually say in this situation would be rather long and complicated. Above was the best I could do. It basically says,

"I like this Anime but what I am watching now are the older episodes. I don't want to watch this because I don't want to know what happens (after the episodes that I am watching now)."

A relatively short if non-literal translation. Does this make sense at all ? I feel exhausted today so probly it's a bit off...



このアニメが好きですが、まだ、見終わっていないので、 結末を先に見てしまいたくないです。
I like that anime, but because I haven't finished watching yet, I don't want to see the end ahead of time.
