If you loved Airwolf as a kid (as I did) then there's no way you can't watch them as an adult.
Tell me that doesn't just get you all giddy inside!
The theme song is of course amazing and the fight scenes are better than I remember (truthfully I didn't think those helos could do a cobra roll and not crash). But the acting and the "plots" are what does it in for me.
On a side note, there's no better era for theme songs than the 80s. Just one right after another, most of shows mid 90s on have forgettable theme songs when you compare it to the 80s shows like Airwolf, A-Team, Knight Rider, CHiPs, Fame, Seaquest, Star Trek TNG, Magnum PI, Night Court, Facts of Life, Thundercats, Inspector Gadget, Fall Guy, St Elsewhere, Dukes of Hazard, Cheers, Dallas, Golden Girls, Seinfeld (89 is when it started), Cosby Show (prefinding out about rapings of course), Charles in Charge, Taxi (80 theme is the one people remembers although it started in 78), Love Boat, Full House, Moonlighting, Pee Wees Playhouse and a TON more. You could go on and on. Most of the theme songs now are huge duds.
