DAD (second half) was definitely very over-the-top but I think not that much more than usual, still only at or arguably even less then level of TSWLM rather than as much as let alone more than Moonraker. I think energy laser going bad was just actually really good idea as was villain who hates but also mimics Bond. It also just worked as being 40th anniversary spectacular and possible, and what it actually ended up being, finale (and dark gritty revenge motivation is part of Bond but pretty small, especially at the time less focused on part).
I'm pretty unsuual in that while GoldenEye is my favorite I think Tomorrow Never Dies is my least favorite, really bland, lacking villain, overhype-y, underwhelming love interest, really perfunctory, uninteresting sidekick and action scenes.
