Lame...there should have been more of a work up to Hank realization moment. 2 episodes worth... And Walt just decides to leave the game behind? Also should have been developed. The rush to end was obvious in the bad plotting.
Walt's a constant, the secondary players-regardless of how much or little they're used-are as well but the true quality of this show directly correlates with how much Jesse's involved which is why this first half season was good but a bit rushed and thin compared to seasons past.
