low star rating lf2 characters in the release projects

[open source nature]

I am back, well i want to talk about the lf2 chars that has low star rating on their project release thread, are they worth for download, or do they have bugs, and should not be downloaded until the creators completely fixed the bugs for the char can be able to get a five star rating. A four star rating char called Leo, i dont understand why he got four star rating and his sprites are drawn so good and the data file is really good and has no bugs so why is that?
