I see, I too know the feeling of an unresponsive audience!
I think the news-parody idea definitely has merit, and judging from the likes and – more specifically – the lack of dislikes, my recommendation would be to continue with the series. I know the numbers are quite small, but if your viewers had a complete adverse reaction to it, I think the dislikes would be very prevalent, which they are not. Another metric that will be telling is your audience retention metric in analytics. If it is very low (say more than 90% leave after the first 30 sec., then that would be a bad sign).
One thing I might recommend though, is to make sure it doesn't turn into a vlog, which I feel happened in this episode. Be sure to watch more news broadcasts, and practise imitating their style of speech (from start till the very end), as well as how the information is presented and organised.
