Some plots can be complex, or just require a little thought but work just as well as a simple one. Others may have been done before but it doesn't mean it is clichéd if it isn't fumbled.

Which brings me to this point.

For the record I only watched a few episodes but I immediately figured out the point of have an episodic plot like it did. Not to mention the massive f*** you to the anime of decades past, that is, a great piece of derision on the dearth of moeblob/otaku shows. The plot fit right in as part of the greater whole of what it was trying to do so I'm not sure how you'd be able to miss something like that. Note that this is just my opinion on the matter, if you still feel strongly about it be a plotless piece of s***, or that any show can have no plot, feel free.
