LFE on this movie should have been 3 paws at best. There was really only 2 stand out bass scenes and you mentioned them in the review. Ice Damn breaking and Table splitting. Other than that nothing really stood out and I have a PB-13 like you.
I think you should maybe scale back the ratings a bit....4 paws for very bass happy movies. Where the LFE is being use and it will really stand out.
5 paws only for movies like Cloverfield or WOTW....
I mean we are getting a little 99 and 100 happy lately
