What does "大したもんだ" mean?


I usually see this phrase in Shonen manga from an antagonist, referring to a
"persistent" character.

I remember a quote that goes like this:

> ほう 大したもんだ。

It was from a character called "Ohm" from One Piece, when found that Roronoa
Zoro was still alive.




大した is used to express admiration for something one finds remarkable or
extraordinary. 大したもんだ or 大したものだ is kind of like saying “You are something” but
it sounds condescending. It may also be used sarcastically.
