Only real complaint I had with Adventure 02 was that T.K. and Kari were treated like pawns. Kari became nothing more then a "damsel in distress" with her only lime in the light being over bickering Davis and T.K. had over her and arguing over her purpose she had as part of the Digi-Destined. Davis wanted her affection and T.K. knew there was more to it then that and it's not exactly pleasing when the love triangle branches over dialogue in the season that drags on forever.
