To be honest, I've rarely seen a scripted show score below 7 and still be watchable
. In fact, under 7.5 usually indicates some serious acting or scripting issues. The lowest I can find of shows I've really loved is "Lexx" at 7.3 and honestly I'd have to put that down to people not realising it was a semi-parody and trying to take it too seriously... because it was amazing
.
This is season-based shows of course. If we venture into soaps there are plenty. Neighbours scores 5.4... And Eastenders scores 4.7
One thing I do find strange though; like I said, a fairly accurate indicator of an even watchable TV show is 7.5+ on IMDB. On the other hand, I'd expect a 7.5+ *movie* to be really quite good... And anything over a 6 is usually OK if its in a genre you like. Under 6 things start to get ropey.
e.g. A 6.5 movie can be a great watch but I'd expect a 6.5 (non-soap) scripted TV show to be abysmal
