Viewer rating upto first decimal point

add decimal system for ratings. just to be more accurate and fair.

add rating system for separate seasons of a tv show.

for example, if i love the first season of a show, i would rate it 9/10 and if i do not like second season of that show, i should be able to rate it as 5/10.

The current IMDb ratings should have smaller ratings increments.  Rather than the 1 point increment, it should be .25 of a point (or something like that).  In my opinion, that gives the IMDb user a way to give a more accurate rating for a t.v. program, film, etc.  

I would like to suggest this change.

Relatively good, though definitely not decimal.

Very probably IMDB have too simple weight system by now which does not distinguish well enough scores.

Normally, people who use scores from 2 to 5 should be somewhere around 3x more weighted than ones who does not use them at all. And people who use only 9 and 10 and 1 much less than both above.

Both because it requires time and accuracy to make your opinion useful, and because it's good bot and arrogance protection.

In that case ratings like 5.5 and 9.5 may be valuable. But very probably you feel need of them not because of this, but because you adjust score distribution to incorrect scale - like you used to mark bad films somewhere near 5, while normally you have 1 and 2 rates for them.

Normally, IMDB must do the scaling and normally you safely use scores form 1 to 5. However, who knows if IMDB implements this properly.

As a sidenote, I'd vote for "7+" "10+" "1-" scores - they do not make ugly decimals, and they allow this extra bit of precision.
