For a post-convert of an iconic film never intended to be viewed in 3D, this is fairly successful with only one or two moments feeling like the characters are cardboard cutouts. The dinosaurs, which is really what we are all here for, sometimes burst out of the screen which definitely adds to the fun.
Fascinatingly, sometimes it is background details which draw your eye eg the stuff on someone's workstation.
The odd bit of blurry looking CGI aside, this film has aged remarkably well. The characters are nearly all well developed and given depth through show rather than tell. Often, a little visual aside such as Grant's firm, but laboured, tying rather than buckling of his seat belt tells you all you need to know.
Verdict: 3D adds something, but not always what you expect.
