Dan once remarked in a thread a few weeks back that Hungarian tv commercials in the 1980's felt like they were 'trying too hard' to seem western. I instinctively knew what what he was talking about but at the same time realize that 'trying too hard' is sometimes an elusive quality that's hard to nail down. It's kinda like saying "we appreciate that you're trying to accomplish a particular aim, but your efforts leave one with an overall impression of either falsity or overkill due to the exaggerated intentionality [of whatever it is you're trying to do]"
Can you think of other perhaps more common examples of trying too hard? Here's one: American craft brewers are trying too hard when it comes to making well-hopped IPA's
or how about when a politician offers a heavily qualified apology? We can all appreciate precision and clarity in speech, but sometimes polticians (and radio talk show hosts) try a little too hard.
