Five things "Smallville" Finale needs

01 Suit & Flight
...and by this I mean not have only 30 seconds in the end where Clark puts on the suit and flies away, but at least in the second part of the finale have him wear it, ultimately it is the last episode of the show at least they can pay off fans that much who followed it for 10 years.

02 Superman Vs Lex Vs Darkseid
...and by any means an epic fight between Superman and Lex and/or Darksied  'Smallville' has a pretty good habbit of not having massive and epic showdowns(except for last season's finale).Before the show leaves the big screens forever fans need to see the long awaited showdown between Clark and Lex.I'm not mentioning Darkseid because I'm not eniterly sure he will go fist-to-fist with Clark.

03 Old characters to share a scene together at least for one last time.
...we know Martha,Chloe and Jonathan returns for the finale.We also know that Jonathan died so besides him it would be nice to see a great scene between Clark,Lois,Tess,Oliver,Chloe and Martha,maybe have Jonathan's spirit present, so we could see them in a scene together.

04 Clark's and Lois' Wedding
...Clark prupossed to Lois back in the episode 'Icarus' but we didn't actually seen the wedding.It would be awesome to have them have their wedding at the begninnig of the finale which would be interrupted by Lex or Darkseid and after defeating them have the wedding "finished" at the very end.Me personally would love the last scene to be between Clark and Lois than have Clark put on the suit only at the very end and fly away.

05 Have Lex kill someone close to Clark
...ultimately he is Clark's ultimate opponent so it would be just right to have him kill someone close to Clark (maybe Chloe or Tess) which would have an impact on Clark's life and fans could really agree that the "real" Lex is back.Maybe have him even kill his own father, Lionel again.Twice...whatever. xD

This is how would I picture the two part series finale of the show.
