I didn't think much of Mon Colle Knights at first, but it did hold my interest, especially after I figured out it was supposed to be a parody. The darker episodes were rather good actually, even if the dub dumbed them down.
Speaking of the dub, it was done horribly. They occasionally cramped two episodes into one, including the introduction episode, they added needles dialogue, changed character traits and names and cut much to make the show more suited for a younger audience and as a result had to re-use a lot of scenes. Also, replacing the Rokumon, a vital part of the show, wasn't a very good move.
Anyway, what managed to survive the cutting sometimes looked pretty good in animation standards and sometimes looked horrid, depending on what studio did the work. The plot for 80 % of the show tends to be rather episodic and are just there for amusement, it's not something you watch for the storyline. The remaining 20 % can be fairly dark though and has more of a continuing story.
In regard to another review, the girl does not bring monsters to life. The monsters are already there, they can be summoned, but all she can do is somewhat communicate with them through empathy.
Also, would someone please fix the episode guide? There are Japanese episodes listed and episodes that never existed. The Saban run of Mon Colle Knights consisted of 45 episodes, the original version had 51. There is no such thing as an episode 79 and manga volumes should not be listed as episodes.moreless
