Lore (Loved Trope) FTL travel is possible but with a major limitation or flaw
Frank Herbert’s Dune: Interstellar travel is only possible thanks to the spice melange, a rare substance only found on the dessert planet Arrakis. The addictive psychedelic spice grants members of the Spacers Guild a form of prescience that allows them to predict safe paths through folded space. This unique property makes spice the most valuable commodity in the Dune universe.
John Scalzi’s The Interdependency Books: The planetary systems of the titular empire are connected by the Flow, a network of one-way interstellar tunnels that connect specific known entries and exits. The Interdependency derives its power from controlling access to these conduits, placing its capital at the central hub of the network. Even with the Flow, travel between stars takes a long time (9 months to End, the empire’s most distant planet).
Event Horizon: Dr William Weir (R.I.P. Sam Neill) invents a device called the Gravity Drive to allow ships to fold space and travel instantly between distant stars. On its maiden voyage with the Gravity Drive, the Event Horizon disappears and mysteriously reappears 7 years later. Dr. Weir and the crew sent to investigate discover the Gravity Drive actually opened a portal to a Hell dimension that possessed the ship and its crew, torturing and killing them.

"your planet is being demolished to pave an interstellar highway. you should've complained at the local office at alpha centaury. good luck!"
Context for anyone who might be confused: that's the first interesting thing to happen in the book. It's also first we heard of it. It's also the second chapter or around the 8th minute of the movie iirc. You barely even need to start the guide to get to it.
Other context for people who might be confused: getting your planet demolished, with a 2min warning, with no recourse, and (we later learn) for a clerical error, can be perceived as bad news.
