Clearly the best of all the seasons. Clark becomes who he is destined to be. We are introduced to several new super heroes. Some return for the final season. Homecoming and Ending episodes are the best of the best. And of course the relationship between Clark and Lois continues to grow and makes you cry.
Is Season 10 the strong overall season of the show? No. Is the show infinitely better focusing on Clark and Lois and Clark's quest to become Superman rather than on Clark and Lana? Of course! Season 10 has some amazing moments. The 200th episode "Homecoming" is certainly an episode all Smallville fans will thoroughly enjoy!
