The first game was very special and had a unique way to tell a simple story. I believe the part 2 will be good based on the trailer but there is no guarantee that the part 2 of last of us will surpass the part one.
Many people loved the first one. Much is not known about Part 2 but Naughty Dog is an amazing developer, we can trust him to come up with something to keep the lovers of part 1 in love with part 2.
The Last of Us is one of the games that people liked so much. The fact that it has a second version excites people. At the same time, it makes them anxious as there is always a possibility that the first one will be better. This second version has a lot to prove and there is a big possibility that it will not disappoint.
From the trailer, it is evident that Ellie is angry and rightfully so because of the events of the first game. She will remain to be feisty and will make the game much more interesting to play. If people would get hooked with the storyline the same way that they liked the first game, then it might succeed the former.
