TLJ's copying of ESB is way more than "a couple of shared plot points," IMO.
ESB: the rebels are holed up on a white snow planet they must escape from. The Force-using character goes to a boggy, desolate planet, where he meets a legendary Jedi Master who's a lot snarkier than he expected, and who's reluctant to train him. Eventually, however, the Jedi Master gets a pep talk from a Force Ghost, and decides to do so. The Force-using character has a disturbing vision in a Dark Side cave regarding his lineage, and runs off before his training is complete. Meanwhile, the main non-Force using character, on a small ship chased by the Empire, goes to a civilian area to meet a potential ally, who double-crosses them. But, at least the guy and woman on this mission may be falling in love? Anyhow, the Force-using character learns a devastating truth about the helmeted Sith enemy (he's his dad!), and the heroes limp away to freedom, but at least they have each other.

And now, a RotJ bonus round!
RotJ: disillusioned by a secret kept by a Jedi elder (that Vader is Luke's dad), the Force-using character willingly surrenders to meet the Sith master and his apprentice, hoping to turn his apprentice back towards the Light Side. The Sith apprentice betrays and kills his master. Around this time, the surviving Jedi Master dies a peaceful death on his boggy, desolate planet.

Yeahhhhhhh... that's a lot of common plot points.
