It rhymes (and that's a good thing).
A partial list of things that crop up in every Star Wars movie, including TFA:
Whilhiem scream (some poor FO Stormtrooper near the beginning of the movie)
Swinging on a rope (Rey repelling down into the ISD wreck)
Subtitles for alien languages (lots!)
Lightsabre fights (duh). This movie featured the second time a blue sabre beat a red one (Anakin vs Dooku round two was the first)
A chase sequence (the very cool getaway chase in the falcon)
C-3po and R2-D2 (naturally)
Big battle (I think the assault on StarKiller counts, but there was a lot of battling through out)
'I have a bad feeling about this.' Han said it this time around.
Queen/princess/senator wardrobe and hairstyle change (Leia again)
Walkways without handrails (OSHA doesn't exist in that galaxy)
In sure there's more. SW has created its own language of visuals and such, has anyone else noticed things that are literally in every movie?
