Gcse spanish - good tv showsWatch
You could also search for the Spanish versions of the shows you used to watch as kid (I'm doing A Level Spanish and watch the Spanish version of Arthur quite a lot ngl ). Good thing about kid shows again is that they usually don't speak that fast so it's easier for you to grasp the vocabulary/grammar structures/pronunciation etc.
You could also try news programmes (CNN Español has a 24hr live stream on Youtube). Keep in mind that they will be speaking very fast so don't feel disheartened if you don't pick a lot up!
Not a TV show but SpanishPod101 on Youtube has a lot of listening activities for beginners to advanced.
If you have Netflix, there are some great Spanish shows on there to get started with. "La Casa de Papel" (Paper House, or 'Money Heist' is a really good one. It's quite popular with English-speakers as well (there's an English dub, but go for the original Spanish). There's also "El Ministerio del Tiempo" (The Ministry of Time) which errs heavily on the historical side of things
