It's terrible, really really bad, but there are some funny bits.
I think everybody knows by now that it's about Sam Jackson having enough of these muthafuckin snakes on this muthafuckin plane, and pretty soon after it came out everybody had enough of the hype and realised it was shite.
The pilot is funny, one bit made me jump, some of the bites are pretty gruesome.
Personally I recommend Eight Legged Freaks.
