C-Tier 'Modern Audience' Story-telling at best, which inspires & intrigues even less than it successfully (attempts to) circumvent, re-write & plagiarize this Classical Tale & Mythology.
Historical inaccuracies aside, the show is just mid, boring, uneventful & an outright slog; and that's (primarily) just in the first 15 minutes of the first Episode. At this pace of riveting & provocative Story-telling, People will indeed need prodigious amounts of Smelling Salts just to keep them conscious by Season One's "mid" point (Pun intended)
If you want a true rendition of this tale which is far more faithful to it's source material, check out the original: 'EXCALIBUR' (1981) -or- 'KING ARTHUR' (2004) (w/ Clive Owen & Kira Knightly)
Both are good films & actually have a Pulse on the Heart of this fantastical Age-old Tale.
