Never forget what Force Awakens was!
I'm afraid in view of Last Jedi criticism some amongst us seem to have become oblivious as to the true nature of TFA: An unoriginal and uncreative fanfic-level rehash, and the root for most current ST problems plaguing the franchise.
Beware! Those who cannot remember the past are condemned to repeat it. Thus:
1. RIP OFF: Within the Saga TFA is the least original and creative entry by far; this in a series primarily known and famous for its imagination:
- Instead of laying the groundwork and plan for a new trilogy with fresh story ideas and characters, TFA just plays as a Best-Of Cover Album.
- TFA rehashes apprximately 80-90% of ANH's plot beats, the rest is OT (father-son conflict; Emperor scenes etc) and some former EU elements; the PT world building is mostly ignored (Coruscant as capital etc);
- TFA uses locations, designs and vehicles from previous films, but is hardly adding anything new (even BB-8 stems from old drawings, other things such as Kylos sabre or outfit are from EU materials);
- The World Building and exposition is shoddy/non-existent: We do not get any idea how and why after RotJ we now have a Bigger, Bader & Dumber Empire again. Or what the FO actually is and how the Republic and the Resistance work;
- All of this is resulting in a stale and stagnant, seemingly shrinking universe ("Shrinking Universe" complaint);
2. CHARACTERS: the character portrayals and actions are incongruent with their character backgrounds;
- This includes racial stereotyping (mostly with Finn: "Droid Pease", runaway slave motive who is given a name by white dude, a black guy tasered by dog-like droid, while being accused of theft by white female, drinks with animals and is starngeled a lot, black guy turns out the janitor etc);
- Blatant Mary Sue writing, which is the writing’s central problem as it sucks out competence and believability of characters and events (e.g., infamous Leia-hugged-first scene, ad hoc powers etc);
- Old canon characters act out of character, especially Han and Luke, and their former arcs and development are ignored; they only serve to glorify/legitimize the new characters*;
* fun fact: that even applies to spaceships, e.g., the Millenium Falcon should be the most famous, recognizable, priceless museum-piece in the galaxy, but the ship is just standing around like "garbage";
- characters are overpowered or too weak, resulting in Video Game like scenes*,
*such as Poe shooting down more than 10 Tie Fighters plus ground groups within one take, or
* Rey saving the day in any situation with untrained ad hoc abilities, including Force power-ups, especially when defeating the main antagonist Kylo; or her getting positions and missions without any rhyme and reason.
* The (trained-from-childhood) soldier Finn is just an incompetent black bumbling fool, and he is finally revealed to be a space janitor (sanatation worker) – he seems mainly to be there to show that other characters are superior and to be theri cheerleader - e.g., cannot fly ships, cannot operate turrets, cannot understand languages, cannot fight, must be rescued all the time etc;
* Some characters such as Kylo are inconsistent, first extremely powerful, then pathetically weak (when facing the untrained scavenger Rey). His inner conflict is poorly developed: e.g., he actually prays to Vader to protect him from the light (!) - thus the guy who is famous for having been redeemed from evil, and having destroyed the Sith/dark side, and who is spooking around as a light side Force ghost...(plot hole²)
- The father/son relationship is badly developed; we never see Han/Ben interact before as father and son, or get an understanding that Kylo is really struggling with having to kill his father – his motivation for going dark side is murky at best;
- The bad guys are underwritten and just pale imitations of previous baddies (Snoke-Emperor, Hux-Tarkin, Captain Phasma-BobaFett)
- Characters lack proper backstories to set them up and to make them interesting; just take Snoke: A powerful, ancient dark side user clone of Palps does not sit well with the previous story (Rule of 2 etc). So what's his story? We know they literally pulled Snoke out of their collective ass...but story wise?
