Yep, this fucking sucked it hard.
I went in not even reading any early reviews, etc, tried my best to go in with an open mind, but upon rewatching all the JP movies, something clearly stuck out to me.....Fallen Kingdom was a bad entry, in fact for sure the worst up to that point. The only caveat was, "well at least we will get the full blown dinos take over America thing" (kind of a bigger followup than what happened in Lost World at least). Instead what happened was almost exactly what HQ feared in the initial post on this thread. They did a fuckin bait and switch bigtime.....tried to explain what happened after Fallen Kingdom in a not so neatly done prologue and then moved on to a totally different (and unsatisfying) direction. To boot, I can't think of any franchise film that brought back legacy characters so ho-humly. I didn't get much nostalgic satisfaction at all with the interplay between all of the three, and in fact I thought their characters were written so piss poorly that I was shocked they got Dern, Goldblum, and Neill back for this shit.
There was a few times I legit wanted to leave the film and not come back, but I thought, well the third act HAS to pay all of this off. The only thing the third act produced was a reasonable enough amount of nostalgia and call-back to the original film (but yet terribly executed though) in parts but none of this really mattered by the end really.
This was not only the worst finale for a franchise I can recall (Matrix 3 had that nod previously I felt) but the 3D was pretty weak, and really all I got was that there was an action sequence in, I believe, the streets of Malta that was pretty awesome. Otherwise, this was a total big fucking turdburger.
