I watched this a few years back and quite enjoyed it, it had some really bad reviews that i think stem from kids who remember the original fondly. i like the original but enjoyed Hoopers remake.
Best film to date no, sorry mate. Texas Chainsaw for me is the pinnacle of horror, totally shits all over The Exorcist in my opinion.
Also i probably like Poltergeist a bit more but that may be due to nostalgia, even more so Salem's Lot which is my second favourite Hooper envisioning, wow that's a big word after 8 beers, think i need a lie down now.
Also Lifeforce needs 2 be taken into consideration due to the madcap crazy nude space vampire shenanigans.
Still like u say, Invaders is well worth a watch, Karen Black n all that.
Someone else mentioned a double bill with Strange Invaders i think. (or did i dream it.?!!) if not then i also enjoyed that too, if i did imagine it then slap me with a kipper.
