How well a fanfic can be done depends on the setting and on the writing talents of the author. Mass effect, for example, has a very large universe and a lot of characters, and the story is not entirely concrete, so you can make it up as you go along. MLP FIM, is a slice of life series, where anything is possible but a lot of stuff that isn't explored, so creativity can run rampant.

Series like Avatar, RWBY and nick's TMNT have an ongoing story, with characters and events that are slowly drip fed, so we don't know what will happen next.

I tend to look out for good, well written fanfiction, usually original flavor stuff that keeps it in the tone of the original, whilst exploring the characters and their setting. (preferebly without shoehorning a love story out of nowhere into it).

Fanfics can fill in plot holes or spaces between scenes, explore alternate paths, or give backstory or an eplogue to certain events. Sometimes doing somthing else, like sending our protagonists to the real world, in space, or having them meet characters from other series.

There are some real gems out there. You just have to know where to look.
