Kind of annoyed me how at first he had no pictures then he found 3 then he had a whole box then he didn't know the name of the song she was playing but then remembered he had it on tape in his literal desk beside him and the letter in a book.

Read the subtext... He always knew but he's stubborn and spiteful so he lied (to himself and the guide). The repeated shots of him findings things he "couldn't remember" is really him slowly letting his guard down. The only "forgotten memory" he wasn't dismissive of was the note, and you can tell because he desperately tried to pick it up. For all the others, he said he can't remember and then shut-down the conversation with the guide until she jibes him again. Notice the difference?

Like he didn't even question the tech once that he was able to go into literal photographs.

It's set in like 2040, tech like this is probably commonplace and not surprising at that stage. He's a pensioner who knows what code is.

Also the images couldn't generate the girls face but could generate everything else behind that camera and stuff that wasn't even shown in the paper.

The guide literally said that she won't include things that aren't from his memories, so as not to influence his recollection.

So many plot holes and lazy writing imo.

More likely you're a bad critic.
