I take great offence in the concept that practical effects are awful. But, yeah. Giant bugs really aren't all that threatening until you give them fire breath or something, I'll give you that. People were only scared of Arachnophobia because OOH, BIG SCARY SPIDER! But damn, spiders aren't that scary when you've faced down Godzilla but angrier and with acid spit/wings.
I'm pretty sure there's a mohair sweater around this house somewhere if I look hard enough.
