I see some great reviews abt this movie. But i didn't like this movie at all. Sorry for being rude, but that's true. May be its just me. The vfx and all in this movie is good. But the thought they have given into the thread of this story, the script and direction, all were average. This would have been a great movie if it released in mid 80s or 90s. Going fwd, spoilers are there, so if you haven't watched the movie yet, don't read further.
When the trailer came out, there were jokes in the comment section that this movie might be Kong and godzilla fighting in the beginning and later they come across a common enemy and fighting as a team against it and winning, well that exactly is the story.
I didn't know 'restarting' someone's heart is as simple as crashing an areal vehicle into the chest.
The hollow earth has constructions like it is human made (is it really? i don't know the history, pardon me if its my mistake)
Kong's axe is powered by the energy source in hollow earth, and during the final battle godzilla powers it up for kong (clichรฉ)
And the side track of mollie boby and frnds have the same old jokes and routines. It was unnecessary. You will be surprised how they easily accesses a highly secured experimental lab by apex, yes it was destroyed by first godzilla attack but still, accessing still functioning (surprisingly) parts of the lab is just something that doesn't makes sense.
There are many more parts like this which i find hard to digest. Don't mind my review and watch the movie and may be you will like it.
