30 Minutes or Less doesn't aim to be great, it just aim to entertain with a simple comedy routine, and succeeds. There's a lot of laughter, derived from very basic situations and dialogs, and lots of action. It's main strength comes from the twists and turns of the story that will pop right to the end. They're not big, but they do break the routine in a very nice way. Add to that some solid, if silly, acting, and it's easy entertainment. The weakness is in the intro, it makes you think you're heading right down a boring unsurprising flick with juvenile humor. Don't get me wrong, it's juvenile alright, but done well.
For entertainment only.
