"Aida" is the first TV show I watched after moving to Spain. Now it's my favorite. I find it very entertaining although I don't always understand the cultural jokes.
This show is centered around the Garcia household, a not-so nuclear family. Aida is the head of the household, and not always the lead role in every episode, despite her name being on it. She tries to keep the rest of her family in line, but they constantly get into trouble...Aida's unemployed brother lives in the house, and also her mother and two children. There are many adventures among them and people around the town, including Paz, Chema, Fidel and Mauricio.
You can imagine this is like a sitcom in the USA, but I think the Spanish censors are a little more relaxed. The plots are about love, relationships, family, friends, work, personal issues, etc. It should be pretty universal even if you're not a native of Aida's country. These days the show comes on Sunday nights.
