The movie was panned by critics and many because of that long scene. Some saw the political agenda, others (like myself) just didn't see any chemistry with Rose and Finn and the entire plot that pretty much almost destroyed the Resistance.
I really enjoyed TFA, loved Rogue One, and am looking forward to the Han Solo movie. I just think that the Last Jedi could hav ebeen so much better, but it wasn't. Its the same level of disappointment I have from watching Episodes 1 and 2.
EDIT: panned by audiences the Critics seemed to love it.
