PPS.tv is an online source of Chinese TV episodes and films. Great for finding input content to improve comprehension and listening ability.
Nearly all of the Chinese shows have Chinese subs as standard. There are also a large number of Western shows/films so if you want to watch something you already know the story of but with Chinese subs/dubs this might be helpful.
On the front page there's a link to download the PPS Player. This desktop application makes it much easier to navigate their huge library of content. Apps are also available for Android and iOS.
If looking for more basic content check out the animations in the 我的小儿卡通 section。喜羊羊与灰太狼 is one of the more accessible shows - it's also one of the relatively few homegrown Chinese shows (rather than Japanese).
Important: PPS is region locked to China so if you are outside China you'll need to VPN into China! There are also unlocking apps available on Android.
