It should be 5.

It's not 5, but it should be.

1. Did they even try?
2. This is painful
3. mediocre
4. below average
5. nothing special but an okay time
6. pretty good, above average
7. great game had a great time
8. A must buy
9. Amazing, goty contender
10. I can't think of how this game could be any better, truly a staple of the generation.

How is "mediocre" worse than "below average"?  

That's the way I see the word 'mediocre' as negative. But if it would help replace that with 'bad' I think I prefer that anyway now you point it out.
