"Losing My Religion"
The two lads are entertaining characters (in themselves) but the script is nowhere near funny enough to sustain a near-5-minute film.
You could trim it down very considerably without losing anything - and you'd gain a lot in comedic value.
Also, the dialogue needs to be more natural.
And, although swearing CAN be funny, there's too much of it and it detracts from the comedy.
"Time Machine"
This is much the better film: it's funny, characterful and believable from start to finish.
But, please cut out the swearing. I've no objection to swearing if it adds to the comedy but, in this film, it seems to stem purely from nerves and lack of confidence.
The two lads are potentially good comedy actors and whoever wrote this is potentially a good comedy writer.
The whole production is obviously a bit rough and ready but, compared to most of the home-made material on YouTube, this is quality stuff.
