I don't really know how the film could've have been executed better, I kinda wanna up my rating to 5 stars. It's near flawless, The easter eggs and the foreshadowing are top notch. It was a load of fun looking at all the fine details in the corners of the screen the whole movie looking for clues.
I guess my only gripe is that he seemed really computer savy but clueless when it came to some things that you'd gather he'd know.
Other than that i'd definitely recommend Searching! The best of the takes place on a computer screen kinda movies.
