Conversely: Stop overthinking Star Wars. I get that people love the universe but the movies are straight up just not deep at all.
They are stealthy enough that an ordinary hunting party can sneak up on an elite Rebel strike force (including a Jedi).
Are we really pretending George was thinking about this while making Jedi? Like in a script review some young guy pipes up: Hey George, how do the Ewoks sneak up on Luke when he has force powers? And George calmly explains, "Well son, Ewoks may look cute but they are actually deadly hunters with expert tracking and stealth skills"
The Ewoks win against the empire because the script says they do. It looks stupid because they are children/(dwarves?) in costumes who can probably barely see what's going on.
I know I'm being a major grump but reading these comments make my eyes roll out of my sockets. It's like watching art critics fawn over an 8 year old's painting because they've been told it's a picasso.
I say all this as someone who enjoys the OT but finds it increasingly embarrassing to admit to having any interest in the property.
