It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.

Ok... Let's be honest. It cannot be the best movie but is quite enjoyable. The movie has the potential to develop a great plot for future movies

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.
