A: No. The show explains everything through jokes. You’ll learn while laughing.
In some Asian territories, legacy Warner Bros. content (which this show is not originally) sometimes ends up on HBO. However, That '70s Show is a Carsey-Werner production, which has complex distribution deals. Always check your local Disney+ or HBO Go, but do not get your hopes up. Netflix or local free-to-air TV (like Trans TV or RCTI+) are historically more likely carriers in Indonesia. Nonton That 70s Show
