Because I didn't watch the previous seasons of it?
Is it good?
Well, not all the parts of Minami-ke is good. But there are hilarious parts here and there, Hosaka's parts being my favourite.
Do I have to watch the first 3 seasons to watch the current one?
Is it a must?
Not really. As long as you watch the 1st season you'll get a general idea of who is who and what is what. I recommend you to watch the 2nd and 3rd reason if you've got some time though, they do have a few good moments.
When I first watched Minami-ke, only the 3rd reason had finished, the OVA's and the 4th weren't released. I had pretty much given up on any further releases after the 3rd season, I only recently found out there were OVA's and the 4th reason.
I've started re-watching Minami-ke from the 1st season yesterday, skipping the boring parts. and rushing to the 4th season. I suppose that's the most effective way; but if you haven't seen Minami-ke before you might miss a few good moments with this method.
My advice is to watch the 1st season then 4th season. If you like them you might wanna give the OVA's and 3rd season a chance. And maybe 2nd season as well.
