If you like Cartman then you might like this episode more than some others but if you think he is just annoying and a spoilt little brat then you will probably think nothing of it. If you love everybody around South Park then you will probably like every episode but probably not like this one much.
I'm sure this episode is enjoyable due to the fact that it maybe everything that you wanted (in that you get to sue people and get everything that they own). A very interesting episode, this one does get silly near to the end though.
:) Okay episode.
