Kinda hard to say, since comedy is so subjective. I found it to be hit or miss myself.
Give it six episodes. Each one is only about 12 minutes, and, depending on which subs you download, they usually come two per file. After the first couple episodes of each season, there's not much continuity, so you can probably even skip an episode if it bores you.
Mint and Milfeulle are cute, the other characters can get a little annoying at times, but its a silly gag comedy, so I don't mind most of the time.
