This film seems confused about what it is trying to accomplish.
On the face of it, the premise seems like a fun movie that you can watch with your kids. Unfortunately, I would not call it a kids movie at all. Aside from the obvious things that parents might take issue with, much of the humor is childish, but obviously aimed at adults.
The movie is also filled with continuity errors, bad editing and pacing, and questionably decent photography. The acting is okay for the most part, with only a handful of examples of egregiously bad performance, and in most of those instances, I would wager it was the result of the poor writing and direction.
As others have pointed out, the vfx are not stellar, but I am going to assume that this was done on a very small budget, with the bulk of the budget going to some of the cameos and gaining access to some of the locations.
The real issue with this film, however, is that it doesn't seem to know what it wants to do. One minute it seems to be a tongue in cheek commentary on the film industry, poking fun at typical movie tropes, the next it seems to want to be a "stranger things" type nostalgia trip (somehow set in modern day, but surrounded by props from every modern time period except today). Then other times it seems to be trying desperately to be a comedy, despite there being zero humor in the script.
It's not the worst film ever made by any stretch, but it is definitely a forgettable film that you will see listed somewhere a year or two from now and think "that sounds interesting" until you start watching and then realize you've already seen it.
