I wrote sometime ago what I thought about season 1 and 2 and, to sum it up, I thought this anime was heavly overrated, I watched the movie and, after 30 minutes, I was thinking how much long of this thing is left?.
To sum up the problems:
1) The main characters keeps doing nothing, he just exists, and do things outside the screen... He's just boring and uninspired.
2) The show is way to long, I don't know why you have 2 make 2 seasons and 1 movie of an anime that could be a fine one with only 1 season at best, the firsts episodes from season 1 were fine but they decided to make it longer, and longer... So yeah, at the end it just gets boring.
3) There's literaly no conflict, I wish they've used the father as a bit more of some kind of antagonist... Or something, there's NOTHING like some kind of plot or anything... It's just 5 cute quintuplets trying to fight over a boring main character that, at the end, choose all of them, which was crystal clear from minute 1 of the anime...
So, at the end, you have plain characters that do what you expect them to do and nothing more for 2 seasons and, the movie, keeps that thing going up... FOR 2 HOURS! Most uninspired confesion I've ever seen in a show. They've should wrap up this show after the first season, make a movie and made things right... But no, they have to get more money from selling figurines from the only thing that the show gives you... 5 cute girls.
So yeah, not recommended and giving it a 4 because I feel generous.
