Think I might have done this one before...
Grabbers (2012)
B-movie throwback, based on a remote Irish island.
After a meteor comes down, the resident Garda (Police) of the island, a scientist, and a couple fishermen, begin to notice odd creatures living in the caves by the shore.
Hence... a night of adventure
Man this film is funny.
Loads of situational comedy, most of it based around alcohol.
Slapstick in buckets too... when the 3 main characters approach a possibly dead creature they grab whatever weapon they have to hand... a chair, a knife, and a rolled up magazine
Then there's moments of inspiration in shooting, including a creature's POV while the main cast are stamping and kicking it in a panicked state.
A lot of the drunk humour (spoken) is pretty daft too, but in a good way.
*Looks at drunk guy*
"How are you still alive?! Have you eaten anything?"
"I had a bag of chips yesterday."
"Right, weapons... what have we got?"
"I have a nailgun, and a board with a nail in it"
"I have a pellet gun"
"What are we going to do with a pellet gun?"
"Shoot pellets........ I don't have any pellets"
*Walks in looking serious*
"Super-soaker, shoots 20 feet. It's my Nephew's."
*Group silence*
"Dibs the watergun"
Even though the creatures are kinda generic in looks (squid crossed with a facehugger), they have a few original quirks to make them differ from the other alien monsters out there in movieland... including how they live off blood, need to be wet to survive, and alcohol is deadly to them.
The CGI and practical effects are also decent for a low budget movie. In fact, better than most major Hollywood movies of late to be totally honest.
Would probably be a borderline entry to my Isolation Horror thread as well.
