We just finished season 2 and are 4-5 episodes into s3 and it seems as if the writers have gotten lazy (which could be a part of why they cancelled it after the third season) - yeah, part of s1 and s2 was like this, but not to the degree of s3…
Every s3 episode is essentially Bode (the youngest Locke) doing something really stupid with a key and bad things happening.
