I’ve never been a fan of [name]Marie[/name]. As a middle name it’s just a ‘filler’ type and I do think it sounds a bit plain/dated/boring as a first name.
I maintain: many boring, “filler” middle names become instantly fresh and powerful when used as a fn. Examples: [name]Anne[/name], [name]June[/name], [name]Hope[/name], etc. [name]Marie[/name] is one of those! I think [name]Marie[/name] as a fn would be original and fun. [name]Marie[/name] as a mn is ‘been there done that time and time again.’
I don’t really like [name]Marie[/name] as a first or middle, not sure why. Probably because it doesn’t have a very exciting sound. But I [name]LOVE[/name] [name]Maria[/name] and just about every other [name]Mary[/name] name from [name]Marianne[/name] to [name]Rosemary[/name].
[name]Marie[/name] is a nice name. I think it’s used way too often as a ‘filler’ middle name as you said, but I’ve actually met many people who use it because it’s a family name or in reference to [name]Mary[/name], the mother of [name]Jesus[/name].
I actually like [name]Marie[/name]. I agree with @tintri -as a middle name I would agree with everyone else. Boring and overdone. But as a first name, it’d be incredibly refreshing.
Sorry, I don’t like it. Definitely plain and dated.
I have to admit, I don’t like the name [name]Marie[/name]. It’s better than [name]Mary[/name], but not my style. I like [name]Marina[/name], though.
east93 and tintri said exactly what I feel about [name]Marie[/name].
I love the “filler” middle names as first names.
Simple and beautiful
I know a 14 year old [name]Marie[/name]. She’s the only one I know! She’s kind of awkward, shy, quiet with bohemian parents that seem old to have a young daughter…but they are very artsy so I kind of thought [name]Marie[/name] was a surprisingly normal pick!
I know a newborn [name]Maria[/name]. The name is adorable on her! Probably more popular, but I find it much lovelier so I understand why.
Plain and uninteresting as a middle, sweet and refreshing as a first. Same as my feelings on [name]Rose[/name].
I’d use it up front or not at all.
My daughter is age 6 and named [name]Marie[/name] :-). I think she’s pretty cute, too.
I started a thread awhile back on [name]Marie[/name]. The consensus was about the same as here, that it is overused as a middle but fresh as a first. I personally love it as a first. It is simple, sweet, and fits a woman of any age.
I agree with @kateri!
It’s definitely overused as a MN, and in that sense, boring, unimaginative, and expected. But as a FN, it’s a bit fresher and unexpected. While it’s not the most terribly exciting of FNs, it does have a simple classiness to it. I know two little girls named [name]Marie[/name], and it’s cute and sweet in the sea of more unique names.
Beautiful and simple as a first name.
It used to be at the top of my middle names list, but I’ve come up with others since. While it may be overused and a filler, if it really goes with the first name, I don’t see a problem with it. 
P.S. - I allllllllways wished it was my middle name.
I love it as a first name (And I wouldn’t use it, but also as a middle name, as it’s my middle name).
It just doesn’t really sparkle for me, but if I had to, I’d MUCH rather use it as a first name any day. I think [name]Marie[/name] is forever doomed as the #1 filler middle name.
Simple and beautiful in my eyes.
It’s my mum’s middle name & she’s always loved it but wished it was her first name. I think as a MN it’s plain & boring but in the first name spot it oozes in beauty & elegance. It has a beautiful sound to it also.
