Doesn't mean it is wrong if all the searches are 'why is the PS5 a pile of shit'.
But you have to be careful with sentiment analysis because as someone has pointed out already, you might be pissed that it is sold out instantly. If you have the more in demand product the amount of people going 'can't buy a fucking PS5 I am pissed' is higher. Equally you have to be careful about the time period you're looking at - are there any events which can cause undue bias.
Most importantly you have to be careful about how you interpret the findings. It doesn't show who is the most popular - it shows what proportion of people who are interested in a given entity are happy about said entity.
