As with any Nolan sibling production, it will always look lame when taken literally because it's hard to tackle subjects like consciousness and the metaphysical, it's always the deeper symbolic and metaphorical message that is conveyed indirectly that makes their creations so special.
For e.g., Inception might look like a simple, straightforward sci-fi flick which might appear lame at times but it tackles some bigger questions about the nature of reality and how memories and emotions work.
That Interstellar scene in the end when he passes the event horizon and transcends into what looks like the higher dimensions of space and time where no separation exists aka singluarity or unity consciousness, he ends up discovering that the one sending messages to him his entire life was no one but himself.
As for Westworld, they again draw parallells between that world and our own. What if we are already pefect beings who are bored of reality and therefore enmesh ourselves in illusory worlds with no real consequences just as a form of entertainment or for personal growth and development under forced limitations.
You might say that maybe I am reading too much into what are simple sci-fi plots but if you follow the conversations in the movies/show closely, that's exactly their intention.
What you did mention are just small problems that need to be overlooked because that isn't the point of the show at all, if you're constantly being pedantic you won't enjoy any of their works ever.
