There are a few possibilities for what you might be looking for:
* Are you looking for a show that's similar to Lost? There are many great shows out there that have similar themes of mystery, adventure, and character development. Perhaps you're looking for something with supernatural elements like Supernatural or The X-Files, or something with a focus on time travel like Dark or Doctor Who.
* Are you looking for the latest episode of a show that airs weekly? If you can remember the name of the show, I can help you find out when and where you can watch it.
* Are you looking for something else entirely? Please tell me more about what you're looking for and I'll do my best to help!
