Basket Case was directed by Mark Kohr. HE also directed Time of Your Life, Hitchin A Ride, WICA, amongst others. He did an excellent job with those videos, they were very cute.
I had no problem with Sam Bayers directions of Oh Love and Kill the DJ. They are much darker songs than any of the songs that Mark Kohr directed. I find Sam Bayers direction more mature and they used him at a time when they were trying to appear more mature, to change their image. Sam Bayer helped them do that with the AI videos.
They were clearly going for a much darker theme with the OH Love and Kill the DJ videos. That is why they chose Sam Bayer. The right director will depend on the direction of the new album. They may want to go back to a funnier themed video or they may want the video to be on the more serious side.
Personally, I don't care who the director is as long as it fits the theme of the song properly.
