Well I know Solo, Slick, and I all really like it. I almost re-watched it again the other day myself.
If you're expecting Saving Private Ryan you will be disappointed.
Personally. I think a lot of people didn't like it because it was a WWII movie without the U.S., something we don't typically see.
I didn't like it because I didn't think it was all that great of a movie. I'm just fine with a WW II not involving the US, heck there aren't that many that we see here so its a nice change of pace, however like I said I didn't think it was all that great of a movie.
