somewhere between 6 or 7 for me.
there were a great string of races, some great performances from Leclerc and Max and, as mentioned, Sainz and Norris were gret fun plus Albon!!!
as for the negatives, title decided early, another year of Ferrari tripping over themselves, and Renault, Haas, RP, Williams were no where (although Haas' antics were entertaining
).
biggest disappointment was Bottas though. clearly he is driving a great car but this season was a step back for him. i like VB and dont wish to be critical but his seat is being wasted and to be fair he is deserving of more criticism then Vettel imo.
but overall, some nice rivalries emerging and with some of the proposed rule changes, i feel encouraged about the direction the sport is heading.
