Query: Nice idea for a Book, however the plot has too many flaws to live up to the potential.

It began as something really interesting and the overall idea for the book has potential however there are numerous flaws such as:1) week characters2) a villain that only shows itself up in a completely unreasonable way and pursues objectives that are also completely unreasonable in the context of the plot3) illogic plot decisions (why it is the geologist that figures out an important scientific puzzle related to quantum mechanics when there is a physicist in the team?)4) a dangerous event that kills many people from a certain group and make the disappear without trace but has no effect on several other people at all.
