I’ll point you to the main thread where this has been discussed extensively:
Replace the 5 star rating system
The long and short of it is that there is no current plan to change the rating system. Given the subjective nature of any rating system, and the fact that the site’s founder @Peter has considered various rating systems, he has settled on the current model. The current five star system based on the scale below was decided upon as the most ideal for the general purposes of Grouvee (you can read more about his position in the thread I linked to above).
- Five stars: loved it
- Four stars: really liked it
- Three stars: liked it
- Two stars: mostly didn’t like it
- One star: did not like it at all
