Post-Credit Scene - WTF? Worst and Laziest Ever.
If you plan on seeing Fallen Kingdom - it's a fun, dino romp. More of the same, but surprisingly small in scope. Dinos are in a mansion the whole time.
If you heard there's an end-credit scene, don't be sucked in to wait for it. It's not done Marvel style at all - doesn't' advance the story in any meaningful way. It literally is 3 seconds long with a pterodactyl landing on Las Vegas spire. Wow. ends movie with a not-again groan, leaving you not wanting more.
