I'm happy to see some love for Predator 2, I've always felt it's one of those underrated sequels that gets unfair hate.
A couple of things I appreciate about it:
Changing the setting to the city. It would have been easy to do a jungle or a remote place again but they changed things up. Getting Danny Glover as a lead who brings a different vibe to Arnie rather than just getting a 'Arnie clone'. The new things they introduce as part of the Predator arsenal are genuinely cool and awesome. The blade, the spear, the net. A lot of sequels would get those elements wrong and add unnecessary things but these are actually cool additions. The scene in the slaughterhouse when they disguise their heat signatures and the predator has another 'frequency' to use to spot them. That's awesome!
On a sidenote I think Predator 2 might just be the sweatiest movie ever. Everyone looks like they're out of a sauna, pretty sure Bill Paxton has big sweat stains in his arm pits in every scene he is in.
