When I was at university and in the few years after that, IMDb was a great resource from movie information. I have a vague recollection of it all being user-generated content, but that is going all the way back to the mid-nineties.
Over the years, I have noticed that every time I look at IMDb, it is less user-friendly and less usable that the last time. Instead of going to IMDb for movie information, I'm using Wikipedia more and more often.
Below is a picture showing the useful information on the Wikipedia page for a TV series. I've highlighted everything here that I consider to be useful content.
And here is the corresponding page from IMDb. If you were to scroll down the page, you would find useful information further down but it's all laid out in such a bland fashion that it's hard to discern content from filler.
I'm really not sure what IMDb is trying to achieve with this page. Whatever it is, I think they are failing because many times when I load an IMDb page, I regret it soon after and go straight to Wikipedia.
