How to talk about completing a series?


I was wondering how to convey "today I've completed reading a manga series" or
"I've completed watching a TV series". Does "Verb(ます stem)+終わる" sound wrong?
Should I use "てしまう"?

Also, how can I say that a series is completed? Meaning that all the volumes
or episodes have been released and are now available. I thought about
"○○シリーズが終わった" but I doubt it sounds natural.




For your completing enjoying any piece of work (not limited to series), you
can simply say [verb]-終わる／終える or 全部 [verb]-る. Verbs are different according to
medium, so 読む for books, 見る (formally 視聴する) for audiovisual (TV, video...),
and 聞く for audio (songs, radio...). ～しまう indeed partially covers such a usage
but not easy to use in this situation.

> この小説を読み終わった _I finished reading this novel._  
>  アニメを13話全部見た _I completed watching (all) 13 episodes of an anime._

There are, however, also a few fancier and terser words frequently used:
読了【どくりょう】（する） and 読破【どくは】（する） for completing books, especially the latter
carries a nuance that you have accomplished a great goal. Anime fans have a
funny figure of speech 完走【かんそう】（する） for watching the whole season, which is
otherwise used when finishing a marathon run or such.

For the second question "a series is completed", I think most people solely
choose the verb 完結【かんけつ】する "(finish and) conclude" to describe any serial
story to reach an end.
