Fairly unimpressed, or just getting old?

I tried watching the much praised first episode of The Last of Us on Binge last night.

I was deeply unimpressed.  OK, the first 5 minutes was pretty well done, but as I said to my son, the next 20 minutes of "the world is suddenly turning zombie and collapsing overnight" is stuff we've seen many times before and there was nothing novel or particularly interesting in how it happened in this story.

The rest of the show was heavy on dialogue, which I didn't think was particularly well written, and the main male and female character don't display much at all in the way of likeability.   I get that the developing dynamic between them is at the heart of the show, but I already don't care for them.

It just feels a very well trodden path of familiar tropes.

This is not a view widely shared amongst critics, although here is one exception.  On Twitter, it seems that many gamers are just ecstatic that the show follows the game so closely, with comparisons of the cut scenes from the game apparently looking at times exactly the same as the scene in the TV show.   Am I supposed to impressed about that?  Why? 

So, I wonder if this is a fair reaction, or a sign that I'm getting old(er)-age cynical of what anyone 30 years or more younger than me likes?    I'm not entirely sure...
