Yes, it saves others from wasting their time. I really disagree with the people that think its fine to sit through 2 or 3 bad seasons because the show gets good later. Either I can skip to later or dont watch.

If I dropped it, I thought it wasn't great, so I'll rate accordingly.

Yeah, I mean, your time is valuable and it isn't going to make it more enjoyable if you've already made your mind up about something by trudging through it more. People talk about slow build and "wait until it reaches the good part!" but quite honestly, if a show takes an awful long time to get to whatever you believe is the good part or at least the meat of the story that makes it interesting, then it's not a good show. It has bad pacing.

I have a gauge of limit as to when I personally rate or judge something. An album has 5 songs to hook me, less if the album is lesser than the standard. A show, has 5 episodes to get me invested, less if it fails the first two episodes. Movies have maybe an honest 15 - 25 minutes not counting slow logo reveals, previews .etc A game has maybe less than 2 hours to get me to want to revisit it.

So on and so forth. People will nag you about how you can't judge things so early, but again, your time is more valuable.

I have never rated a show regardless of finishing it. What do you all rate it on? The service you watched it or something 3rd party like rotten tomatoes?

Yes I rate shows I drop. I’ll drop a show because it is bad or some part of it overshadows the good parts.

The most recent example is Scarpetta. The serial killer investigation aspects, the dual time lines (part of the show involves the characters in the 90s, part is modern day) and many other aspects of the show are excellent.

One of the characters is played by Jamie Lee Curtis and her character is just too over the top and insufferable that it makes the show unwatchable, for me. I get what the show is trying to do with the character, i am just not dealing with that.

Yes, but only if you have atleast watched a season worth of content. I think it is okay to rate a show from season 1 forinstance. And being able to chance your opinion about it if season 2 rocks your world out of the blue. I mean, I don't need to watch the whole sex and the city to understand the show isn't for me. But am I going to rate it from my personal præferences? No, that wouldn't really give people who likes these types of shows the correct score in the end.

Not usually, I cant think of a time that I have to be honest, but I usually understand that I'm not the target audience and give uo, or I got distracted by something more pressing and forgot all about it.

I try to rate whatever so it shows up when I look people up, as in what else they've been in. Mostly IMDb but that doesn't work for anime (doesn't always show the English cast).
