Enjoyable but one HUGE plot hole among others

Rating: 6/10 (5 March 2019)

As the credits began to roll I was ready to give this movie a 9 or 10 out of 10. But after having a short time to critically analyze what I just watched, I realized it has a huge plot hole that kind of ruins it for me.
Plot hole: Alex Jones is said to have a driver's license which is completely implausible. Even if the state of Pennsylvania would grant someone with the IQ of a 10 year old a license, there's no way he could have been issued one with the name Alex Jones considering the real Alex Jones died long ago. I don't understand why the aunt would let her kidnap victim drive around in the first place, even if he is "brain-washed". But apparently she also must've took him into the DMV, presumably showed them the birth certificate and/or social security card of the real Alex Jones (her deceased son) and the state then proceeds to issue a driver's license to a person who has been deceased for years.
Even if the aunt had managed to pass him off as Alex Jones to the state/DMV, when Alex was brought in for questioning early in the movie, police would have identified him as being the aunt's child (since that's who the real Alex Jones was) which would raise extreme suspicion when both Alex and the aunt said the nature of their relationship was nephew/aunt, not son/mother.
It may seem like a minor detail, but without the license extreme suspicion would have been brought upon Alex and the aunt at the very beginning of the investigation and the movie/investigation would've been over MUCH quicker.
Very disappointed that seemingly almost no one else notices this massive plot hole, even 99% of the people that pointed out several other (more minor) plot holes.
Even though the movie has a massive plot hole, I still give it a 6 as the other aspects of the movie were so well done that I'd rather watch this than 50% of other movies, a lot of which are just terrible. At least this movie kept me wildly entertained and engaged, which I can't say about a whole lot of other movies.
