The Invoklines 7
 

These two look like the might actually be decent. I've only seen Tremors I. Bloodlines looks alright, but it also looks like they might be trying to hard with the campyness(campiness? spellchecker doesn't like either one).

Haven't seen The Invoking, but the trailer makes The Invoking II appear to be a solid 5/10. Which means worth a watch.
