Don't remember about the other seasons, but my favorite on the 4th season is too far gone, with no other to match it. Hershel's death totally broke my heart, but that's the point, we are watching apocalypse, and it's good to see your own hopes crushed once in a while. His dead and the Governor's failed redemption was all I needed to get down to their reality.
Season 1= Days Gone Bye, First episode of series where we get to meet the characters.
Season 2= Pretty Much Dead Already, I liked the ending, which is kinda the main reason I like this episode.
Season 3= Welcome To The Tombs, I like this episode, mainly because it was well-plotted. The only flaw was Andrea's death. The only good episode Glen Mazara wrote in S3.
Season 4= After, It gave us more character development than action, which is better. I don't care about the action, I am far more interested in the characters coping with the aftermath of a zombie apocalypse.
Out of the entire Series I think Too Far Gone is the best, the right amount of Action, Drama, and Tragedy, The Acting was amazing and The Governor is shown to have become a true monster(He already was) in killing Hershel the way he did. Also have to say i love Hershel but he got the greatest/most memorable death in the show,
but Season wise
S1: Days Gone By(Runner Up: TS-19)
S2: Beside The Dying Fire(Runner Up: Pretty Much Already Dead)
S3: Clear(Runner Up: between Made To Suffer/This Sorrowful Life)
S4: Too Far Gone(Runner Up: A, with The Grove close behind it)
Season 3: Hounded (Runner up: This Sorrowful Life)
Season 4: Too Far Gone (Runner up: The Grove)
Least Favortie Episodes:
Season 1: Wildfire (Still liked it, but it was really depressing.)
Season 2: Nebraska (Not saying it's terrible or anything. I still liked it, but it sorta dragged.)
Season 3: Walk With Me (Too boring and focused entirely on Andrea.)
Season 4: Dead Weight (Episode dragged, it was way too boring, and we already had one episode focused on The Governor. We didn't need another one.)
I take back what I say about Too Far Gone being the best episode. That has been dethroned to runner up after seeing A. This season finale really did make up for last season's finale. I think the most intense part aside from that cliffhanger ending, was the part where Joe's group finds Rick, Carl and Michonne. I've seen gruesome stuff in this show, but seeing the part where Rick literally rips open Joe's throat with his teeth really takes the cake with gruesome parts. It's one thing when a walker does it, but when a living person does it? That's pretty crazy. Afterwards, Rick goes psycho on the guy that tried to rape Carl, and literally mutilates him. I'd say he got a burst of insanity back at that one moment in the episode and then regains it after reuniting with Daryl.
Now, back to the ending. The ending to this episode has opened many questions for me. We find out that Terminus really is a trap. I knew right from the start that Terminus was bad news. We have no knowledge of Beth's whereabouts still, and now we have no idea where Tyreese and Carol are. With the way this season ended, I assume that Season 5 is going to pick up right where Season 4 ended off. This is a true cliffhanger right here.
The way Season 1 ended, it felt like a good end to the Atlanta Camp/CDC story arc. Season 2 seemed like a suitable ending to the Farm story arc. They left the farm and the camera pans to show the prison in the distance. Season 3 ended very poorly. All we get out of that ending was that more people moved to the prison and Andrea is dead. Season 4 ended with Rick saying to his group that Terminus screwed with the wrong people. It ends at that and now we are left wondering what their next course of action is. All I know is, Season 5 is going to have a pretty bad ass beginning.
In my opinion, Season 4 was probably the best season of the entire series. Who knows what my opinion of Season 5 will be. I'll figure that out in October.
