I love 24 and LOVE Sopranos, but they are two completely different shows. The acting and characters and writing on the Sopranos outclasses just about anything on television.
Sure, there's way less drama and action but the plot lines are so much more intricacte and they really show a more accurate depiction of real humans, even if the mob premise is rather unrealistic itself.
Point being, if you're looking for nonstop action, the Sopranos just may not be the show for you...so far this season has been the best since Season 3 and the first episodes have been incredible so far in my opinion.
And the dream sequences are INCREDIBLE imo
