I think better quality, script and production companies are subjective to one's opinions. There's no qualitative measures that show Ch3 is better than Ch7 or Ch7 is better than Ch3 in any way, other than in the ratings department. But then ratings are typically only a reflection of the popularity of the lakorn amongst the audience, so I don't necessarily think that good ratings=good quality or good script. I know that while not all, but most people do watch lakorns based on who's starring in it. If your favorite actors or actresses are starring in it wouldn't you watch it? And if more people watched then that means more ratings. And if you liked it, then wouldn't your opinions be biased when asked about the quality, script, or the production company?
Sorry for the questions. I was just trying to explain that people always say Ch7 lakorns are crap, but are they sure they don't think it's crap because they're biased about it? Same with Ch3 too. Lots of people think Ch3 portrays too much risque love scenes or do they think it's too indecent because they're used to seeing "imagine it yourself" love scenes from Ch7? So you see, it's all about people's opinions.
