Many fans of AMC's hit show The Walking Dead were disappointed with Season 7, which saw Rick and his crew outmuscled every step of the way by Negan and the Saviors, which led to an oppressive and underwhelming season in the minds of most long-time fans. But the Season 8 premiere, also the show's 100th episode, came out with guns blazing. You can almost hear Twisted Sister's "We're Not Gonna Take It" as Rick and his unified band of allies finally started the "All-Out-War" that fans have been clamoring for ever since Negan came on the scene. That being said, there were 5 defining moments of Sunday night's debut episode of Season 8 of The Walking Dead.

The first moment that comes to mind is definitely the opening scene and montage that revolved around Rick rallying the troops. The plan is definitely being set and to really drive the point home, viewers were treated to a montage of Daryl and Rick taking out all of the lookout points used by the Saviors. Rick reminds the team that it's their world and not Negan's while declaring that it's time to take him and the Saviors out. All in all, this was a very effective way to start the 100th episode with a bang.

The second moment comes when Rick and his team finally make it to Negan and the Saviors compound. It was made abundantly clear to viewers early on in the episode that, following the events of the Season 7 finale, the Alexandrians have now united with the residents of the Hilltop and the residents of the Kingdom, to finally dispose of Negan and the Saviors. Under the leadership of Rick, Maggie, Ezekiel and Jesus, the team has decided that there is no time like the present to attack.

The next moment is the actual first spark of the all-out-war that we've all heard so much about. However, Negan did have a trick up his sleeve with Gregory, the leader of the Hilltop crew, but Jesus promptly made sure that they stayed put, alongside Rick. Rick and crew then decide to open fire on Negan and The Saviors, but they end up shooting out most of the windows, which either means that this was a part of the plan that was lost in translation through the multiple montages, or the crew is really bad at firing guns. The RV, rigged with explosives also rams into the compound, but obviously, Negan escapes while Rick can't quite figure out how to aim his gun.

Next up, Father Gabriel is found stuck in a room with Negan where he is repeatedly asked if he has his "sh!tting pants" on. Apparently, Gabriel is going to need said pants to hang with Negan and the growing number of Zombies congregating outside. All because that traitor Gregory stole his car. Gabriel is clearly not having a good day and it appears that his days are going to get a lot worse before they get any better thanks to his new pal Negan.

Finally, the last moment has to be the true star of the episode, Old Man Rick. It's still not clear where Old Man Rick fits into Season 8, but he is prominently featured in the first episode of the season, leading many to believe that this could be an alternate timeline or even an idyllic dream that Rick has for the future that will only come true by taking out Negan and the Saviors at any cost. We'll just have to wait and see where the blissful times of Old Man Rick fit into the rest of Season 8 of The Walking Dead. While we wait for episode 2, check out what AMC considers to be the most talked about scene in the season 8 premiere below.
