If you want to replace class sessions that go along with Genki, I think TokiniAndy is your best bet: https://www.youtube.com/playlist?list=PLA_RcUI8km1NMhiEebcbqdlcHv_2ngbO2
I also really like iroiro as another comment mentioned. He has a comprehensible input playlist for complete beginners - it has a ton of pictures, pretty slow speech, it's very understandable.
Between those, you should be off to a good start.
